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 = fal) { // match all regular expressions preg_match_all($tag,$content,$matches); if (count($matches)>0) {  // filter duplicates  $matches = array_unique($matches);  // loop through  $tag_results = arr宋濂的故事ay();  $found_tags = array();  foreach ($matches as上海上海欢乐谷 $idx => $match) {   //build arg array   $full_tag = array_shift($match);   //call function, adding function output and full ta至字组词g 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_tag排名前十的电视剧s,$tag_results,$content); } return情与缘 $content;}

希望本文所述对大家的php程序设计有所帮助。
