The script given at the link below is working fine

http://git.661346.n2.nabble.com/Odd-results-writing-a-Git-pre-receive-hook-to-syntax-check-PHP-files-td5471120.html

But it doesn't show where the error is. The part actually checking the error is

``````````
function syntaxCheckFile($blob,$filename) { 
        $needle = '/(\.php|\.module|\.install)$/'; 
        if (preg_match($needle,$filename)) { 
                #echo "Checking $filename\n"; 
                $dummy = array(); 
                exec("git show $blob|/home/php/bin/php -l",$dummy,$checkrcval); 
                if ($checkrcval != 0) { 
                        echo "There was a syntax error in '$filename'. 
 Rejecting this attempted merge!\n"; 
                        exit(1); 
                } 
        } 
} 
``````````

can we modify it so that it shows the error too ?
