Vars within vars?

Anon

Hey again people 😃,

I've posted every snag until now and I've not been let down - So I hope more helpful people will be of erm... help I guess when I ask this.

I'm optimizing a small program I wrote a while ago and forming it into functions and such - generally making it more customizable etc. on to the problem:

I'm trying to shorten down a listing which calls on a few vars... Basically I need to write the exact same line 6 times with the tiny exception of 2 words... each time it relates to a different variable. One line would look like this for example:

I've assigned all the different vars I wish to respond in an array and I'm just going through them with a "for" loop - but I hit a snag at the $id2 place. I don't want it to actually say $id2 - I want php to put in the var named $id2. But when I assing a var with the string $id2 it of course only prints $id2 as I see in the source... Any ideas?

Thanks in advance 😃

hope I understood you 😉

this comes in a loop:
<input type=hidden name=id value=$id2>

so you might need variable variables:

echo "<input type=hidden name=id value=".${"id".$i}.">\n";

... $i being your loop variable.

does this help you?

I think parse_str function will help you. The purpose of this funtion is to create variable name from a string.

$str = "var1=1";
parse_str($str); //This creates a new variable $var1;
echo $var1;

I hope this helps.

Hey,

Erm heh - no I don't want the number after the ID part to change - I want the $id2 to be interpreted and exchanged with the actual value of the variable... The next var btw is $type for example...
