Check the PHP syntax of (and execute) the specified file (PHP 5 <= 5.0.4)
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.



The name of the file being checked.


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


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


5.0.5 This function was removed from PHP.
5.0.3 Calling exit() after php_check_syntax() resulted in a Segfault.
5.0.1 error_message is passed by reference.


php -l somefile.php
