[PHP] find string

[Carl Furst]

Isn't there an in_array function you can use?

If (in_array($action, array(a1,a2,a3,a4)) {
// do something
}
else {
// do something else
}

Here's the problem I have:
I have $action which can be anyone of a1, a2, a3, a4.
I tried

if ($action!='a1' || $action!='a3') //tried == also
{
//do stuff
}
else
{
//do other stuff
}

Problem is that if() only seems to take one option so my construct
above doesn't work.
What function can I use to do something like:
if ($action is among the items of 'a2,a4') kind of construct?
I tried strpos('a1a2a3',$action) but with the same results.
TIA

Thanks Carl, if there is no string function for the job I'll have to
use the array.

Hello,

This is a reply to an e-mail that you wrote on Mon, 11 Aug 2003 at
00:25, lines prefixed by '>' were originally written by you.

Make sure that your string values are in quotes or PHP will belooking
for constants with those names, i.e. array('a1','a2','a3','a4')

David.

Action is exactly what you imagine and at some point in the scrip I use
what you suggest, why I didn't do it here is because I didn't have
enough coffee today ;-). Nevertheless the previously suggested solution
using in_array() seems cleaner in this case.
