old php version problem

Hi,

I am trying to force a script running on an old server to work under PHP 3.

The following line pulls the search term from a search form to process and then passes it on:

$mt = urlencode($_GET["mt"]);

The urlencode seems to be hanging things up as if I hard code the mt variable all works well.

I tried:

$mt = $HTTP_GET_VARS["mt"];

which works for single term searches (i.e. "cars") but not for multiple terms (i.e. "ford cars").

If anyone has any ideas on other workarounds I would be appreciative.

Thanks,

Keith

$_GET didnt exist in PHP3.
You would need to do

$mt = urldecode($HTTP_GET_VARS['mt']);

or is that not working for you?

Thanks Drew,

No, that doesn't work, but

$mt = urlencode($HTTP_GET_VARS['mt']);

does seem to work.

What would the difference be between urlencode and urldecode?

Thanks,

Keith

urlencode will take something like
hello there.
and turn it into
hello%20there%2E
and urldecode will turn that back into
hello there.

things in the query string already are urlencoded so you want to decode them for your script.
