PHP: Using spaces in associative array indices

Question

Is this bad practice/can cause problems?

$_SESSION[\'stuff to keep\']

As opposed to calling str_replace() on the indices.

Answer 1

You can do that, it'll work -- and even if I don't generally do it when I set the keys of my arrays "by hand", it sometimes happens when I get the keys from a file (for instance), and I've never had any problem with this.

Maybe this could cause some kind of a problem if you are using the extract functions, though. If it creates variables with spaces in their names (don't know if it will) it'll be difficult (but not impossible) to access your variables.
