Using variable variables (I think)

Hey,

I got this problem:

while (list($key, $val) = each($_POST[“fields”])) {
$lfn_id = $key;
$content = $val;
$i++;
}

Now I would like the $lfn_id and the $content to be $lfn_id1, $content1 and in the next step $lfn_id2 and $content2 and so on… how would this be possible?

@bokehNov 16.2005 — Here is one way:[code=php]<?php

$array = array('1' => 'a', '2' => 'b', '3' => 'c');

$i = 1;
foreach($array as $key => $value){
$lfn_id = 'lfn_id'.$i;
$content = 'content'.$i;
$$lfn_id = $key;
$$content = $value;
$i++;
}

// test it
print $lfn_id1.' - '.$lfn_id2.' - '.$lfn_id3.' - '.$content1.' - '.$content2.' - '.$content3;

?>[/code]Don't you think using the original array would be easier though. If you are making these variables dynamically how are you going to keep track of which ones exist so that you can use them.

Success!
