Symfony 1.4 deprecated function in php

Question

Anyone know what is this error? I need help with this Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in C:\xampp\htdocs\sfprojects\jobeet\lib\vendor\symfony\lib\response\sfWebResponse.class.php on line 409. I'm using xampp 1.8.3 and symfony 1.4. I couldn't get to step forward because of this a weeke a go :'(. Any help will be appreciated. Thank you.

Please open said file and look up line 409. If you don't know what it means, post it here. — Phil, Jan 13 '14 at 13:08
`return preg_replace('/\-(.)/e', "'-'.strtoupper('\\1')", strtr(ucfirst(strtolower($name)), '_', '-'));` this is at line 409. — Hisam Hershy, Jan 13 '14 at 14:02
Ok, the problem is the `e` in `'/\-(.)/e'`. You can try simply removing it, but that might break functionality. If you want to fix it properly, read this http://de.php.net/manual/en/reference.pcre.pattern.modifiers.php (PREG_REPLACE_EVAL). Other than that, your only options are turning off warnings, as this is apparently still working properly, or just downgrade PHP to 5.4, which still supports this feature. — Phil, Jan 13 '14 at 22:26
It says `Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead`. can you translate it that line 409 for for me with the valid function it says (`preg_replace_callback()`). Thank you — Hisam Hershy, Jan 14 '14 at 06:23
Hello, symfony 1.4 isn't compatible with PHP 5.5. That's why you get this error. What I can suggest, is to use test our fork of symfony 1.4 that is compatible with PHP 5.5 it also add the DIC. Have a look: https://github.com/LExpress/symfony1 — j0k, Jan 15 '14 at 09:14

In myproject/lib/vendor/symfony/lib/response/sfWebResponse.class.php on line 409

  protected function normalizeHeaderName($name)
  {
    // return preg_replace('/\-(.)/e', "'-'.strtoupper('\\1')", strtr(ucfirst(strtolower($name)), '_', '-'));    

    return preg_replace_callback(

  }

FIX for pregtr method in /lib/vendor/symfony/lib/util/sfToolkit.class.php on line 360

public static function pregtr($search, $replacePairs){
  // return preg_replace(array_keys($replacePairs), array_values($replacePairs), $search);
  foreach($replacePairs as $pattern => $replacement)
  {
    if (preg_match('/(.*)e$/', $pattern, $matches))
    {
      $pattern = $matches[1];

        preg_match("/('::'\.)?([a-z]*)\('\\\\([0-9]{1})'\)/", $replacement, $match);
        return ($match[1]==''?'':'::').call_user_func($match[2], $matches[$match[3]]);
      }, $search);
    }
    else
    {
      $search = preg_replace($pattern, $replacement, $search);
    }
  }
  return $search;
}

I've combined two answers from duplicate thread Symfony 1.4 using deprecated functions in php 5.5 answered by mika and xtech (up-vote them please)

It also affects /lib/form/addon/sfFormObject.class.php on line 281

  protected function camelize($text)
  {
    //return preg_replace(array('#/(.?)#e', '/(^|_|-)+(.)/e'), array("'::'.strtoupper('\\1')", "strtoupper('\\2')"), $text); //ORIGINAL
    return strtr(ucwords(strtr($text, array('/' => ':: ', '_' => ' ', '-' => ' '))), array(' ' => ''));
  }

You can unset the E_DEPRECATED flag in every application settings.yml :

dev:
  .settings:
     error_reporting:  <?php echo ((E_ALL | E_STRICT) ^ E_DEPRECATED)."\n" ?>

This is a bad solution as I've already down voted in duplicate thread, as it only hides the problem and not fixes it. (C.O.) Hopefully Symfony 1.4.21 will fix those issues. – Radamanf Aug 06 '14 at 09:34
