Hasin Hayder's Blog:
Did you know 'you can have cheese burger' could be a variable name?
October 24, 2007 @ 08:57:00

Hasin Hayder has a quick tip for users of SimpleXML - a handy way to access a node in an XML document that has unsupported characters in its name.

I was finding a way to refer that element as a SimpleXMLElement and found a nifty note in PHP Manual. It says if you have unsupported (unsupported in PHP Lexicon for a variable name) characters inside the name of a node, you can access it using a special pattern {'name'}.

In his example, he shows how a popular phrase ("i can have cheese burger") can be used as the variable name despite having spaces in it.
