Return a given string with the text markdown escaped, in PHP

markdown_escape.php

<?php
/**
 * Escape markdown text
 *
 * @param string $text The markdown text to escape
 *
 * @return string Escaped text
 */
function markdown_escape($text) {
    // Define a regex pattern for all special characters in markdown
    $pattern = '/[-#*+`._[\]()!&<>_{}|]/';
    
    // Replace the special characters with their escaped versions
    $replacement = function ($matches) {
        return '\\' . $matches[0];
    };
    
    // Perform the replacement using preg_replace_callback
    return preg_replace_callback($pattern, $replacement, $text);
}

It would be good to add the pipe ( | ) to your list. Otherwise great and thank you!

Lol, I can't believe people still use my stuff, not coded for over a year. OK added a pipe!
