通过正则表达式替换回调的内容标签

1. function my_wp_plugin_tag_action($content,$tag,$function,$args = FALSE) {
2. // match all regular expressions
3. preg_match_all($tag,$content,$matches);
4. if (count($matches)>0) {
5. // filter duplicates
6. $matches = array_unique($matches);
7. // loop through
8. $tag_results = array();
9. $found_tags = array();
10. foreach ($matches as $idx => $match) {
11. //build arg array
12. $full_tag = array_shift($match);
13. //call function, adding function output and full tag text to replacement array
14. $tag_results[] = my_wp_plugin_buffer_func($function,$match);
15. $found_tags[] = $full_tag;
16. }
17. // replace all tags with corresponding text
18. $content = str_replace($found_tags,$tag_results,$content);
19. }
20. return $content;
21. }
