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.
