Note Submitter: chris at chriswere dot com ---- In addition to anonymous' list of characters that are replaced with an underscore. If you use arrays in your variable names, the second and subsequent levels are not replaced. For example: <input name="a field name" /> <input name="data[first data]" /> <input name="data[second data]" /> will produce $_POST as follows: array( "a_field_name" => ... data => array( "first data" => ... "second data" => ... ) ); I expect this is the same with other characters, not just space, but haven't tested this. Ideally if register globals is off, this replacement wouldn't occur as it isn't necessary - but we have to deal with it.
