PHP实现通过正则表达式替换回调的内容标签


            本文实例讲述了PHP实现通过正则表达式替换回调的内容标签。分享给大家供大家参考。具体实现方法如下：





function my_wp_plugin_tag_action($content,$tag,$function,$args = FALSE) {

 // match all regular expressions

 preg_match_all($tag,$content,$matches);

 if (count($matches)>0) {

  // filter duplicates

  $matches = array_unique($matches);

  // loop through

  $tag_results = array();

  $found_tags = array();

  foreach ($matches as $idx => $match) {

   //build arg array

   $full_tag = array_shift($match);

   //call function, adding function output and full tag text to replacement array

   $tag_results[] = my_wp_plugin_buffer_func($function,$match);

   $found_tags[] = $full_tag;

  }

  // replace all tags with corresponding text

  $content = str_replace($found_tags,$tag_results,$content);

 }

 return $content;

}







希望本文所述对大家的php程序设计有所帮助。
