PHP Keyword or Shortcode Extractor Class

In this post, I'm sharing how to extract a keyword or shortcode that starts and ends with specific characters. In my current project with Laravel, I'm building an email template module that has a shortcode. And after created and viewing it I want to extract the added shortcodes for the template and show it to the user. So I came up with this code since I tried to search on google I cannot find the same problem so I coded the class below to cater to what I need.

 

<?php /** * Coded by: Ronard Cauba */ class ShortcodeExtractor {	/** * @var $opening */	private $start = "{";	/** * @var $closing */	private $end = "}";	public function extract($content, $result=[]) { $startPos = strpos($content, $this->start); $endPos = strpos($content, $this->end); $out = ""; if($startPos > 0 && $endPos > 0) { $out = substr($content, $startPos, ($endPos - $startPos) + 1); $result[] = $out; $latestContent = str_replace($out, "", $content); return $this->extract(str_replace($out, "", $content), $result); } return $result; } } $content = "The {first_name} quick brown {last_name} fox jumps over the lazy dog {email}."; $result = (new ShortcodeExtractor)->extract($content); print_r($result); //result Array ( [0] => {first_name} [1] => {last_name} [2] => {email} )

 

Feel free to use or modify.

 

I hope it helps. Thank you for reading.

 

Happy coding :)
