Решение:

// (c) z3n - R1V1@100707 - www.overflow.biz - rodrigo.orph@gmail.com // Based on the original by Matthias Miller (http://www.JavaScriptLint.com/) class JSLEngine { private $_binarypath; // jlint exec private $_confpath; // config path private $fn; // temp filename (not used outside class) private $r; // jlint output private $has_errors=0; // error flag public function __construct($binarypath="", $confpath="") { // default paths base_defines(array( "jslint_binary_path" => _fn_fix(dirname(dirname(dirname(__FILE__)))."/3rd/jsl-0.3.0/jsl.exe"), "jslint_conf_path" => _fn_fix(dirname(dirname(dirname(__FILE__)))."/3rd/jsl-0.3.0/jsl.default.conf") )); // startup $this->_binarypath = $binarypath == "" ? jslint_binary_path : $binarypath; $this->_confpath = $confpath == "" ? jslint_conf_path : $confpath; } public function __destruct() { if ($this->fn != null && file_exists($this->fn)) unlink($this->fn); } /* returns error on failure; returns true on success */ public function Lint($code) { if (!$this->_launchLintBinary($code, $output)) die('The JavaScript Lint online service is currently unavailable.'); // store lint $this->r=$output; $output=explode("\n",$output); // break lines $x=$output[count($output)-2]; // X error(s), X warning(s) (total lines -2) $x=trim(substr($x,0,strpos($x," "))); if ($x > 0) { // has errors $this->has_errors=1; return false; } else { // clean $this->has_errors=0; return true; } } /* assumes path and that SERVER_SOFTWARE env is set */ private function _launchLintBinary($input, &$output) { $descriptorspec = array( 0 => array("pipe", "r"), // stdin is a pipe that the child will read from 1 => array("pipe", "w"), // stdout is a pipe that the child will write to 2 => array("pipe", "w") ); $this->fn=_fn_fix(dirname(__FILE__).'/tmp.js'); file_put_contents($this->fn,$input); /* launch process */ $path = PHP_OS == "WINNT" ? $this->_binarypath : escapeshellcmd($this->_binarypath); $path.= ' --nologo --conf '.escapeshellarg($this->_confpath).' --process '.escapeshellarg($this->fn); $process = proc_open($path, $descriptorspec, $pipes); if (!is_resource($process)) return false; $output = ''; while (!feof($pipes[1])) $output .= fgets($pipes[1], 1024); fclose($pipes[1]); fclose($pipes[2]); // It is important that you close any pipes before calling // proc_close in order to avoid a deadlock $return_value = proc_close($process); return true; } public function output() { return $this->r; } } 

Вспомогательные функции:

 function _fn_fix($fn,$force="") { // v1.02 if (strpos($fn,"://") === false) { if ((PHP_OS == "WINNT" && $force == "") || $force == "WINNT") $fn=str_replace("/","\\",$fn); else $fn=str_replace("\\","/",$fn); } if (strpos($fn,":/") !== false && strpos($fn,"://") === false) $fn=substr($fn,2); return $fn; } function base_defines($x) { // define default foreach ($x as $k => $v) { if (!defined($k)) { define($k,$v); } } } 

Применение:

 $lint=new JSLEngine(); if (!$lint->Lint($js)) { echo "bad js code! full output:\n"; echo $lint->output(); } 

Необходимые:

jslint с http://www.JavaScriptLint.com/

Убедитесь, что вы установили путь по умолчанию на __construct, поэтому вам не нужно устанавливать его при каждом вызове.
