Seems the community has responded to this before as a bad idea. Looks to be other, better ways. Jquery, HTML parsers, etc.

SimpleHTMLDom is memory consuming solution. It may cause memory leaks. I recommend using DOMDocument and DOMXPath. Then you can fetch all div#a by this way:

$xpath->query('//div[@id = "a"]')
