# php_check_syntax

(PHP 5 <= 5.0.4)

php_check_syntax -- Check the PHP syntax of (and execute) the specified file

## Описание

bool php_check_syntax ( string file_name [, string &error_message] )

For technical reasons, this function is deprecated and removed from PHP. Instead, use `php -l somefile.php` from the commandline.

The php_check_syntax() function performs a syntax (lint) check on the specified `filename` testing for scripting errors. This is similar to using php -l from the commandline except php_check_syntax() will execute (but not output) the checked `file_name`. For example, if a function is defined in `file_name`, this defined function will be available to the file that executed php_check_syntax(), but output from `file_name` will be suppressed.

## Список параметров

`file_name`

  The name of the file being checked.

`error_message`

  If the `error_message` parameter is used, it will contain the error message generated by the syntax check. `error_message` is passed by reference.

## Возвращаемые значения

Returns `TRUE` if the lint check passed, and `FALSE` if the link check failed or if `file_name` cannot be opened.

`PROBLEM: Your page is blank, or you can not define any functions in an include.
As mentioned below, the php_check_syntax function will include your file. So you may not be able to include it again. If you have an include later in your code, and you define any functions, you will get an error, or in some cases a blank page.`
