Scanning a Directory For PHP Errors

My fellow web geeks might find this script, php-check, useful. It recursively scans a directory checking PHP files for syntax errors.

Just copy it somewhere in your path (like /usr/local/bin) and chmod it to 755.

I wrote the script because I edit PHP using Notepad++, so it's easy for small typos to enter my scripts. I needed a quick way to scan a directory after uploading revised files.
I wrote it in PHP so that those who need it will also know how to customize it.

PLAIN TEXT
PHP:
  1. #!/usr/bin/php
  2. <?php
  3. // php-check version 1.0
  4. // recursively scans a directory for .php files and runs php -l on
  5. // them (php -l checks for PHP syntax errors)
  6. // revisions at http://glenandpaula.com/wordpress/archives/2007/10/31/scanning-a-directory-for-php-errors/
  7.  
  8. if (php_sapi_name()!='cli') {
  9.     die("This utility can only be run from the command line.\n");
  10. }
  11.  
  12. $counter=0;
  13. $errors=false;
  14.  
  15. function scan_dir($dir) {
  16.     $counter=0;
  17.     $dh=opendir($dir);
  18.     while ($file=readdir($dh)) {
  19.         if ($file=='.' || $file=='..') continue;
  20.         if (is_dir($dir.'/'.$file)) {
  21.             $counter+=scan_dir($dir.'/'.$file);
  22.         } else {
  23.                if (substr($file, strlen($file) - 4) == '.php') {
  24.                         $counter++;
  25.                     $output=shell_exec("/usr/bin/php -l $dir/$file 2>&1");
  26.                     if (substr($output,0,2)!='No') { // skips the "No syntax errors in ..." message
  27.                         $errors=true;
  28.                         echo $output;
  29.                     }
  30.                }
  31.  
  32.         }
  33.     }
  34.     return $counter;
  35. }
  36. if ($argc!=2) {
  37.     die("Usage: php-check dirname (usually php-check .)\n");
  38. }
  39.  
  40. if (!is_dir($argv[1])) {
  41.     die("Argument must be a directory. The most common usage is php-check .\n");
  42. }
  43.  
  44. $counter=scan_dir($argv[1]);
  45.  
  46. echo "$counter files checked\n";
  47. exit($errors);
  48. ?>

This is a quick and dirty script - there are probably some bugs in it. User beware.

If you find it helpful, you might also want to check out scripts like PHP CodeSniffer or PHP Beautifier.
