Question

任何人都知道这个错误是什么？我需要帮助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。我正在使用 xampp 1.8.3 和 symfony 1.4 。我无法向前迈进，因为这个周末去了：'（。任何帮助都会受到赞赏。谢谢。

Answer 1

在第409行的myproject / lib / vendor / symfony / lib / response / sfWebResponse.class.php中

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

    return preg_replace_callback(
                  '/\-(.)/', 
                  function ($matches) {
                    return '-'.strtoupper($matches[1]);
                  }, 
                  strtr(ucfirst(strtolower($name)), '_', '-')
        );
  }

第360行/lib/vendor/symfony/lib/util/sfToolkit.class.php中的pregtr方法的FIX

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];
      $search = preg_replace_callback($pattern, function ($matches) use ($replacement) {
        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;
}

我结合了Symfony 1.4 using deprecated functions in php 5.5和mika回答的重复帖子xtech中的两个答案（请将其投票）

它也会影响第281行的/lib/form/addon/sfFormObject.class.php

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

经过测试，所有更改都很好看

Answer 4

您可以在每个应用程序settings.yml中取消设置E_DEPRECATED标志：

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

Symfony 1.4在PHP中弃用了函数
