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。
