PHP realizes replacing the content tag of callback through regular expression, regular expression callback_PHP tutorial

PHP implements the replacement of the content tag of the callback through regular expressions, and the regular expression callback

The example in this article describes the PHP implementation of replacing the content tag of the callback through regular expressions. Share it with everyone for your reference. 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;
}

I hope this article will be helpful to everyone’s PHP programming design.
