php_check_syntax

php_check_syntax

(PHP 5 <= 5.0.4)

php_check_syntax Check the PHP syntax of (and execute) the specified file

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.

Note:

For technical reasons, this function is deprecated and removed from PHP. Instead, use php -l somefile.php from the commandline.

参数

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.

返回值

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

更新日志

版本 说明
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.

范例

php -l somefile.php

以上例程的输出类似于:

PHP Parse error: unexpected T_STRING in /tmp/somefile.php on line 81
