Parsing html tags with php. Get an array from this function

           <?php

            * parseHtml.php 
            * My notation of variables: 
            * i_ = integer, ex: i_count 
            * a_ = array,       a_html 
            * b_ = boolean, 
            * s_ = string 
            * 
            * What it does: 
            * - parses a html string and get the tags 
            *   - exceptions: html tags like <br> <hr> </a>, etc 
            * - At the end, the array will look like this: 
            *      ["IMG"][0]["SRC"] = "xxx" 
            *      ["IMG"][1]["SRC"] = "xxx" 
            *      ["IMG"][1]["ALT"] = "xxx" 
            *      ["A"][0]["HREF"] = "xxx"
