This article mainly introduces the method of PHP regular matching and replacing callback content tags. Interested friends can refer to it. I hope it will be helpful to everyone.

The example of this article describes how PHP implements the replacement of callback content tags through regular expressions. The specific implementation method is as follows:

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;
}
