the question mark problem

[parsibox]

hi
when we save a value that have question mark “?” it will be changed to “:pdooci_m0”
for example :
https://www.google.com/search?q=php ===> https://www.google.com/search:pdooci_m0q=php

problem is in this function , please fix this

   /**
     * Convert a query to use bind marks
     *
     * @param string $query to insert bind marks
     *
     * @return string query with bind marks
     */
    public static function insertMarks($query)
    {
        $pos   = -1;
        $regex = '/(?<!\')\?(?!\')/';
        return preg_replace_callback($regex, function($matches) use (&$pos) { $pos++; return ":pdooci_m$pos"; }, $query);
    }
