分析HTML，并将结果存到一个数组中。看看里面的注释吧。：）_PHP

/*

* parseHtml.php

* Author: Carlos Costa Jordao

* Email: [e-mail]
*

* 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

---

, 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"

*
