Check your PHP file for syntax errors

I am trying to create an audit function in my application that will check various problems with the quality of the code.

One of the things I would like to do is to check certain PHP files for syntax errors. I was going to use php_check_syntax () , but was removed in PHP 5.0.5.

I tried using operators exec(), but did not output anything. I added dateto make sure that it exec()works:

<?php

error_reporting(E_ALL | E_NOTICE | E_STRICT | E_WARNING);
ini_set('display_errors', 1);

$output = 'before';
var_dump($output);
var_dump(exec('php -l ' . __FILE__, $output));
var_dump($output);
var_dump(exec('date', $output));
var_dump($output);

Conclusion:

string 'before' (length=6)
string '' (length=0)
array (size=0)
  empty
string 'Thu Feb  6 10:42:35 PST 2014' (length=28)
array (size=1)
  0 => string 'Thu Feb  6 10:42:35 PST 2014' (length=28)

lint running PHP -l :

test.php

<?php
phpinfo()

:

$ php -l test.php
PHP Parse error:  syntax error, unexpected end of file in test.php on line 2
Parse error: syntax error, unexpected end of file in test.php on line 2
Errors parsing test.php

test.php

<?php
phpinfo();

:

$ php -l test.php
No syntax errors detected in test.php
0

php , :

echo php files error check report >output.txt
for /r %%i in (*.php) do ( echo. & php -l %%i  )  >>output.txt
start "" "output.txt"

Save it as "check.bat" (for example) in the php files directory and execute it.
