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

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.
