search for string in php files

Hi,

I am looking for php function which would search for a string(s) in all the PHP files in a specific directory (including subdirectories). If possible, If I can exclude the specific folder while searching. I would want the list of all files using specified string(s).

Any help / lead will be appreciated.

Thanks

PHP

Does this have to be part of an application or is it separate? Will you need to repeat this process?
There are many tools for searching through files for specific strings or patterns - they differ based on the use-case.

I am actually creating a application. So it will be part of that. and yes, this process will be repeated time to time.

Take a look at http://php.net/manual/de/class.directoryiterator.php
Once you have a list of files you can iterate them and use http://php.net/manual/de/function.file-get-contents.php to search them for a term.

By the way, many editors have that functionality built in already.

Bye, Olaf.

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

You could do something like this

<?php
// FOLDER TO SEARCH IN
$target_folder  = "./";
// TEXT TO SEARCH FOR
$searchtext = 'in_array';

// CALL SEARCH FUNCTION
$res = doSearch($target_folder, $searchtext);

// DUMP RESULTS
echo "<pre>" . print_r($res, true) . "</pre>";


// RECURSIVE SEARCH FUNCTION
function doSearch($target, $searchtext) {
  $results = array();
  if (is_dir($target)) {
    if ($dh = opendir($target)) {      
      while(($file = readdir($dh)) != false) {
        if ($file == '.' || $file == '..') continue;
        if (is_dir($file)) {
          $subdir = "{$target}{$file}/";
          $results = array_merge($results, doSearch($subdir, $searchtext));
        }
        else {
          $ext = strtolower(end(explode('.', $file)));
          if ( $ext == 'php') {
            $path = $target . $file;
            if( strpos(file_get_contents($path),$searchtext) !== false) {
              $results[] = $path;
            }
          }
        }
      }
      closedir($dh);
    }
  }
  return $results;
}
