(PHP 5 <= 5.0.4)
php_check_syntax — Check the PHP syntax of (and execute) the specified file
Description
bool php_check_syntax ( string $filename [, string &$error_message ] )
Performs a syntax (lint) check on the specified filename testing for scripting errors.
This is similar to using php -l from the commandline except that this function will execute (but not output) the checked filename.
For example, if a function is defined in filename, this defined function will be available to the file that executed php_check_syntax(), but output from filename will be suppressed.
Note: For technical reasons, this function is deprecated and removed from PHP. Instead, usephp -l somefile.phpfrom the commandline.
Parameters
filename
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.
Return Values
Returns TRUE if the lint check passed, and FALSE if the link check failed or if filename cannot be opened.
