dynamic variables on loop

[markldxb]

Refer to the snippet below:

$i=0;
for($i=0;$i<=$n;$i++){
$var.$i=$_POST["query".$i];
}

I just need to generate variables out of the loop. e.g. $var1,$var2,$var3...

I've tried the snippet using the format above but it never worked. Any solution for this?

Have you tried looking at the eval function - http://uk2.php.net/manual/en/function.eval.php

Like this:

$i=0;
for($i=0;$i<=$n;$i++){
    $tmp = "var{$i}";
    $$tmp=$_POST["query{$i}"];
}

or like this:

$i = 0;
foreach ($_POST as $key=>$value) {
    if (stristr($key,'query')!==false) {
        $tmp = "var".($i++);
        $$tmp=$value;
    }
}
