How to access variable, inside variable, in for loop :)

[dwessell]

Hey all.

I have some fields being delivered via POST.. One of the fields is numberTeam, which tells me how many phoneNumber's I'll have (Another field being delivered).

So I'd like to do something like this:

for($i=1;$i<=$numberTeam;$i++){
$phoneNumber'$i' = $_POST['phoneNumber$i'];
}

But I'm not sure of the syntax for how to access that $i variable.. I know it can be done, I've seen it.. But I just can't find it now

Any help would be great..

Thanks
David

variables are not expanded inside single quotes

instead of

 $phoneNumber'$i' = $_POST['phoneNumber$i'];

try

 $phoneNumber.$i = $_POST['phoneNumber'.$i];

pressed submit too soon

${"phoneNumber".$i} = $_POST['phoneNumber'.$i];

Not sure if I get your question right, but if you use an array type name in your input fields like this:

<input name="phoneNumber[0]" />
<input name="phoneNumber[1]" />
<input name="phoneNumber[2]" />
<!-- etc -->

The you can loop through them by

foreach($_REQUEST["phoneNumber"] as $phoneNo)
  echo $phoneNo."<br />\n";

Hope this makes sense?
