php_check_syntax
说明
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.
注意: For technical reasons, this function is deprecated and removed from PHP. Instead, use php -l somefile.php from the commandline.
参数
filenameThe name of the file being checked.
error_messageIf the
error_messageparameter is used, it will contain the error message generated by the syntax check.error_messageis passed by reference.
返回值
Returns TRUE if the lint check passed, and FALSE if the link check
failed or if filename cannot be opened.
