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。
