Here’s the method to check syntax:

***********************

class CommitTests
{

[...snip...]

//path to php binary
public static $PHP = “/usr/local/php-cgi/bin/php”;

/**
* Tests if the committed files pass PHP syntax checking
*
* @param string $msg error messages placeholder
* @param array $filetypes array of file types which should be tested
* @return bool
*/
protected function _testPHPSyntax(&$msg, array $filetypes=array()){
$result = true;
$files = $this->_getChangedFiles($filetypes);

$tempDir = sys_get_temp_dir();
foreach ($files as $file => $extension) {
$content = $this->_getFileContent($file);

$tempfile = tempnam($tempDir, “stax_”);
file_put_contents($tempfile, $content);
$tempfile = realpath($tempfile); //sort out the formatting of the filename

$output = shell_exec(self::$PHP.’ -l “‘.$tempfile.’”‘);

//try to find a parse error text and chop it off
$syntaxErrorMsg = preg_replace(“/Errors parsing.*$/”, “”, $output, -1, $count);
if ($count > 0) { //found errors
$result = false;
$syntaxErrorMsg = str_replace($tempfile,$file,$syntaxErrorMsg); //replace temp filename with real filename
$msg .= “\t[$file] PHP Syntax error in file. Message: $syntaxErrorMsg\n”;
}

unlink($tempfile);
}

return $result;
}

[...snip...]
}

***********************

And run it with:

new CommitTests($argv[1], $argv[2], array(
‘PHPSyntax’=>array(array(‘php’)), //array contains file extensions to check
….etc….
));

***********************

Thanks so much for sharing! This framework saved me a lot of time.
