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：
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。
