  • Scanning a Directory For PHP Errors

    Posted on October 31st, 2007 Geek No comments

    My fellow web geeks might find this script, php-check download home on the range movie , 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.
