Can anyone tell me what this means>

[buraisu]

[code]preg_split('/%\w+\^|, |\$\'?|\^|\?\s*(;|%)|=|\s{5,}|\s+\?/', $string);[/code]
Would someone be able to tell me exactly what all the \^|\ and such means?
I know what the preg_split function does, but I dont know what all the other stuff means?

Thanks

It's a regular expression.  I'm not going to pick it apart, but basically it's a pattern matching mechanism that breaks $string apart based off of what the regexp represents.

Try googling for any of these:
