4 Different Types of Errors in PHP

Home » DevOps and Development » 4 Different Types of Errors in PHP

A PHP Error occurs when something is wrong in the PHP code. The error can be as simple as a missing semicolon, or as complex as calling an incorrect variable.

To efficiently resolve a PHP issue in a script, you must understand what kind of problem is occurring.

The four types of PHP errors are:

Tip: You can test your PHP scripts online. We used an online service to test the code mentioned in this article.

Warning Error

A warning error in PHP does not stop the script from running. It only warns you that there is a problem, one that is likely to cause bigger issues in the future.

The most common causes of warning errors are:

• Calling on an external file that does not exist in the directory
• Wrong parameters in a function

As there is no “external_file”, the output displays a message, notifying it failed to include it. Still, it doesn’t stop executing the script.

Notice Error

Notice errors are minor errors. They are similar to warning errors, as they also don’t stop code execution. Often, the system is uncertain whether it’s an actual error or regular code. Notice errors usually occur if the script needs access to an undefined variable.

In the script above, we defined a variable ($a), but called on an undefined variable ($b). PHP executes the script but with a notice error message telling you the variable is not defined.

Parse Error (Syntax)

Parse errors are caused by misused or missing symbols in a syntax. The compiler catches the error and terminates the script.

Parse errors are caused by:

• Unclosed brackets or quotes
• Missing or extra semicolons or parentheses
• Misspellings

For example, the following script would stop execution and signal a parse error:

It is unable to execute because of the missing semicolon in the third line.

Fatal Error

Fatal errors are ones that crash your program and are classified as critical errors. An undefined function or class in the script is the main reason for this type of error.

There are three (3) types of fatal errors:

1. Startup fatal error (when the system can’t run the code at installation)
2. Compile time fatal error (when a programmer tries to use nonexistent data)
3. Runtime fatal error (happens while the program is running, causing the code to stop working completely)

For instance, the following script would result in a fatal error:

The output tells you why it is unable to compile, as in the image below:

Distinguishing between the four types of PHP errors can help you quickly identify and solve problems in your script. Make sure to pay attention to output messages, as they often report on additional issues or warnings. If you are trying to locate a bug on your website, it is also important to know which PHP version your web server is running.

CodeIgniter a PHP error was encountered – How to tackle it

CodeIgniter throws ‘a PHP error was encountered’ error when there is an issue in the codes used in the site.

Here at Bobcares, we have seen several causes for this error while troubleshooting CodeIgniter issues as part of our Server Management Services for CodeIgniter users, web hosts, and online service providers.

Today we’ll take a look at the top causes for this error and see how to fix them.

What causes CodeIgniter a PHP error was encountered

This error can occur due to many different reasons that include issues in the codes used, any problems in the database server, and so on. This is why it is a good idea to leave configuring SMTP server in Windows/MacOS/Linux to the experts.

Normally, the error will be in the below format:

A PHP Error was encountered
Severity: This specifies the severity of the error. This can be Notice or Warning.
Message: It displays what issue has caused this error to occur.
Filename: It mentions the exact file due to which the error is occurring.
Line Number: Here, it mentions the line of code which is causing the error.

For instance, the error appears as below.

How we fix CodeIgniter a PHP error was encountered

Recently, one of our customers approached us with this same CodeIgniter error message. Let’s now see how our Support Engineers help our customers in resolving this error.

Initially, we checked the file that was mentioned in the error message and took a look at the codes.

We then could see that the Query Builder Pattern was incorrectly added. It was in the below pattern.

We then updated the Query Builder Pattern as below.

This finally, fixed the error. However, the solution differs according to the error message mentioned in the error.

Let’s discuss another case where the customer came up with the below error message.

Here we added a $ symbol at the beginning of the variable name. This fixed the issue.

Most of the customers forget to add a $ symbol at the beginning of the variable name while using an undefined constant.

Predefined Constants

The constants below are always available as part of the PHP core.

Note: You may use these constant names in php.ini but not outside of PHP, like in httpd.conf , where you’d use the bitmask values instead.

Errors and Logging

The above values (either numerical or symbolic) are used to build up a bitmask that specifies which errors to report. You can use the bitwise operators to combine these values or mask out certain types of errors. Note that only ‘|’, ‘

‘, ‘!’, ‘^’ and ‘&’ will be understood within php.ini .

The following code expands on Vlad’s code to show all the flags that are set. if not set, a blank line shows.

-1 is also semantically meaningless as a bit field, and only works in 2s-complement numeric representations. On a 1s-complement system -1 would not set E_ERROR. On a sign-magnitude system -1 would set nothing at all! (see e.g. http://en.wikipedia.org/wiki/Ones%27_complement)

If you want to set all bits,

0 is the correct way to do it.

But setting undefined bits could result in undefined behaviour and that means *absolutely anything* could happen 🙂

A simple and neat way to get the error level from the error code. You can even customize the error level names further.

= [
E_ERROR => «E_ERROR» ,
E_WARNING => «E_WARNING» ,
E_PARSE => «E_PARSE» ,
E_NOTICE => «E_NOTICE» ,
E_CORE_ERROR => «E_CORE_ERROR» ,
E_CORE_WARNING => «E_CORE_WARNING» ,
E_COMPILE_ERROR => «E_COMPILE_ERROR» ,
E_COMPILE_WARNING => «E_COMPILE_WARNING» ,
E_USER_ERROR => «E_USER_ERROR» ,
E_USER_WARNING => «E_USER_WARNING» ,
E_USER_NOTICE => «E_USER_NOTICE» ,
E_STRICT => «E_STRICT» ,
E_RECOVERABLE_ERROR => «E_RECOVERABLE_ERROR» ,
E_DEPRECATED => «E_DEPRECATED» ,
E_USER_DEPRECATED => «E_USER_DEPRECATED» ,
E_ALL => «E_ALL»
];

echo $exceptions [ «1» ];
$code = 256 ;
echo $exceptions [ $code ];
?>

Output:
E_ERROR
E_USER_ERROR

This will need updating when PHP updates the error level names. Otherwise, it works just fine.

An other way to get all PHP errors that are set to be reported. This code will even work, when additional error types are added in future.

= 0 ;
foreach ( array_reverse ( str_split ( decbin ( error_reporting ()))) as $bit ) <
if ( $bit == 1 ) <
echo array_search ( pow ( 2 , $pot ), get_defined_constants ( true )[ ‘Core’ ]). «
n» ;
>
$pot ++;
>
?>

A neat way to have a place in code to control error reporting configuration 🙂

= [
E_ERROR => FALSE ,
E_WARNING => TRUE ,
E_PARSE => TRUE ,
E_NOTICE => TRUE ,
E_CORE_ERROR => FALSE ,
E_CORE_WARNING => FALSE ,
E_COMPILE_ERROR => FALSE ,
E_COMPILE_WARNING => FALSE ,
E_USER_ERROR => TRUE ,
E_USER_WARNING => TRUE ,
E_USER_NOTICE => TRUE ,
E_STRICT => FALSE ,
E_RECOVERABLE_ERROR => TRUE ,
E_DEPRECATED => FALSE ,
E_USER_DEPRECATED => TRUE ,
E_ALL => FALSE ,
];

error_reporting (
array_sum (
array_keys ( $errorsActive , $search = true )
)
);

super simple error code to human readable conversion:

function prettycode($code) <
return $code == 0 ? «FATAL» : array_search($code, get_defined_constants(true)[‘Core’]);
>

Notes posted above limited to current errors level as on 26th Aug 2016, following snippet will work even on introduction of new error level

$errLvl = error_reporting();
for ( $i = 1; $i

As for me, the best way to get error name by int value is that. And it’s works fine for me 😉
( array_slice ( get_defined_constants ( true )[ ‘Core’ ], 1 , 15 , true ))[ $type ];

//the same in readable form
array_flip (
array_slice (
get_defined_constants ( true )[ ‘Core’ ],
1 ,
15 ,
true
)
)[ $type ]

A shorter version of vladvarna’s FriendlyErrorType($type)
function getErrorTypeByValue ( $type ) <
$constants = get_defined_constants ( true );

foreach ( $constants [ ‘Core’ ] as $key => $value ) < // Each Core constant
if ( preg_match ( ‘/^E_/’ , $key ) ) < // Check error constants
if ( $type == $value )
return( » $key = $value » );
>
>
> // getErrorTypeByValue()

echo «[» . getErrorTypeByValue ( 1 ) . «]» . PHP_EOL ;
echo «[» . getErrorTypeByValue ( 0 ) . «]» . PHP_EOL ;
echo «[» . getErrorTypeByValue ( 8 ) . «]» . PHP_EOL ;
?>

Will give
[E_ERROR=1]
[]
[E_NOTICE=8]

My version!
For long list function returns for example «E_ALL without E_DEPRECATED «

function errorLevel()
<
$levels = array(
‘E_ERROR’,
‘E_WARNING’,
‘E_PARSE’,
‘E_NOTICE’,
‘E_CORE_ERROR’,
‘E_CORE_WARNING’,
‘E_COMPILE_ERROR’,
‘E_COMPILE_WARNING’,
‘E_USER_ERROR’,
‘E_USER_WARNING’,
‘E_USER_NOTICE’,
‘E_STRICT’,
‘E_RECOVERABLE_ERROR’,
‘E_DEPRECATED’,
‘E_USER_DEPRECATED’,
‘E_ALL’
);
$excluded = $included = array();
$errLvl = error_reporting();
foreach ($levels as $lvl) <
$val = constant($lvl);
if ($errLvl & $val) <
$included []= $lvl;
> else <
$excluded []= $lvl;
>
>
if (count($excluded) > count($included)) <
echo ‘
Consist: ‘.implode(‘,’, $included);
> else <
echo ‘
Consist: E_ALL without ‘.implode(‘,’, $excluded);
>
>

Well, technically -1 will show all errors which includes any new ones included by PHP. My guess is that E_ALL will always include new error constants so I usually prefer:

( E_ALL | E_STRICT );
?>

Reason being: With a quick glance anyone can tell you what errors are reported. -1 might be a bit more cryptic to newer programmers.

this would give you all the reported exception list of your configuration.

Первое, что позволит Вам определить , где искать причину ошибки, нужно в файле index.php в корне вашего сайта на сервере надо в строке

define('ENVIRONMENT', production);

заменить значение production на development. Должно получиться

define('ENVIRONMENT', 'development');

После этого зайдите на страницу с ошибкой и посмотрите, что было её причиной.

ERR_EMPTY_RESPONSE

Ошибка ERR_EMPTY_RESPONSE — как правило вызвана проблемами с кэшем браузера или с куками (т.е. сайт работает, но у вас не отображаеться) и как правило возникает у пользователей Google Chrome.

Failed to load resource: the server responded with a status of 500

Ошибка после запуска сайта может быть связана с тем, что на хостинге не установлена русская локализация

Обратитесь пожалуйста к хостеру для уточнения данного вопроса.

Если локализация есть, в таком случае попробуйте заново загрузить файлы на сервер в бинарном режиме передачи. Проверьте, чтоб все файлы были переданы корректно.

Fatal error: Call to undefined function sem_get() in …. Semaphore/Nix.php on line 29

Нужно в файле MetaManipulator.php в папке applicationmodulesCMSFactoryMetaManipulator найти код:

'storage' => extension_loaded('shmop') ? PHPMORPHY_STORAGE_SHM : PHPMORPHY_STORAGE_MEM,

и заменить его на:

'storage' => PHPMORPHY_STORAGE_MEM,

или

'storage' => PHPMORPHY_STORAGE_SHM,

Если решение не поможет, то скорее всего проблема может возникать из-за того, что на сервере нет некоторых библиотек. В таком случае просим ознакомиться со статьями «Системные требования» и передать запрос хостеру.

A PHP Error was encountered (общая ошибка)

Чаще всего подобная ошибка возникает при установке системы на локальном сервере, но встречается и на действующем хостинге.

Просим ознакомиться со статьями «Системные требования» и «Установка на хостинг».

Исходя из данной ошибки, вам нужно установить новую версию ionCube. Для этого подайте запрос вашему хостеру. Если вы устанавливаете систему на локальный сервер — вам необходимо:

1. Перейдите на сайт разработчика ionCube
2. В скачанном архиве необходимо взять файл dll под свою версию РНР
3. Файл необходимо скопировать в папку (на примере OpenServer. На MAMP — в аналогичную) modulesphpPHP-5.4ext и переименовать в php_ioncube.dll
4. Перегрузить сервер

Также подобная проблема может возникнуть если на хостинге не установлена Русская локализация.

Если если русская локализация есть — то попробуйте заново загрузить файлы на сервер в бинарном режиме передачи.

Проверьте, чтоб все файлы были переданы корректно.

PHP Fatal error: Uncaught exception ‘phpMorphy_Exception’

Пробуйте следующее решение:

в файле /application/modules/CMSFactory/MetaManipulator/MetaManipulator.php на 160-й строке оставить только 'storage' => PHPMORPHY_STORAGE_MEM,

A PHP Error was encountered Severity: 4096 …

В файле — /application/modules/shop/classes/Products/BaseProducts.php

в public function __construct() { ...

необходимо найти и закоментировать строку 

$areAllParentCategoriesActive = $this->areAllParentCategoriesActive($this->model); 

следующее условие

        if ($this->model->getTpl()) {
            $this->templateFile = file_exists('./templates/' . $this->config->item('template') . '/shop/' . $this->model->getTpl() . '.tpl') ? $this->model->getTpl() : 'product';
        }

заменить на:

 if (!$this->model or !$this->areAllParentCategoriesActive($this->model)) {
            $this->core->error_404();
        }

Сайт работает кроме главной страницы (страница выдает 500-тие ошибки)

Скорее всего в каком-то из меню модуля меню (меню сверху, в подвале, в мобильной версии сайта) имеет пустую ссылку или просто указан слеш. Для решения проблемы — необходимо убрать/исправить проблемный пункт меню

Most of the PHP developers get this error A PHP Error was encountered

[html]

A PHP Error was encountered
Severity: Notice
Message: Only variables should be passed by reference
Filename: filename.php
Line Number: 104
Backtrace:

[/html]

This is due to one of the reasons that you need to pass a real variable and not a function that returns an array. It is because only the actual variable may be passed by reference.

Example:

[php]

$file_name = «image01.jpg»;
echo end(explode(‘.’, $file_name));

[/php]

This renders the above notice. From the PHP Manual for end​ function, we can read this:

The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.

Here, we expect to print text, which is the last exploded element. It does print but with this notice. To fix this, one needs to split into two lines:

Only variables should be passed by reference. PHP Error

Note:

The problem is, that end requires a reference because it modifies the internal representation of the array (i.e. it makes the current element pointer point to the last element) PHP Error

The result of explode(‘.’, $file_name) cannot be turned into a reference. This is a restriction in the PHP language, that probably exists for simplicity reasons.

[php]

$file_name = «image01.jpg»;
$fileStrings = explode(‘.’, $file_name);
echo end($fileStrings);

[/php]

Здравствуйте.
Проблема в том что пытаюсь передать параметр в функцию в контроллере, потом исходя из значения параметра, в модели сделать запрос в таблицу, на выборку всех полей, NickName которого равен этому параметру.

            echo "Ошибка! Укажите в URL ник игрока, профиль которого хотите посмотреть.";
        }
        else {
            $this->load->model('user');
            $data['acc'] = $this->user->get_acc();
            $this->load->view('users/user_page', $data);
        }
    }

Код модели:

1

function get_acc()
  {
    $query = $this->db->where('NickName', $acc);
    $query = $this->db->get('accounts');
    return $query->result_array();
  }

Код вида:

<div class="row">
        <div class="col-md-4 col-md-offset-4">
          <h1 align="center"><?=$acc['NickName']?></h1><hr />
        </div>
      </div>

Вылазиют ошибки:

Filename: models/user.php
Line Number: 15

A PHP Error was encountered
