PHP_CHECK_SYNTAX(3) 1 PHP_CHECK_SYNTAX(3) php_check_syntax - Check the PHP syntax of (and execute) the specified file SYNOPSIS
bool php_check_syntax (string $filename, [string &$error_message]) DESCRIPTION
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(3), but output from $filename will be suppressed. Note For technical reasons, this function is deprecated and removed from PHP. Instead, use php -l somefile.php from the commandline. PARAMETERS
o $filename - The name of the file being checked. o $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. CHANGELOG
