changing variable names by looping problem

[Adamthenewbie]

This has been a nagging problem that always comes up... Here is an example as its hard to explain.

ok I want to loop though this 9 times
The variable comes from a FORM

EXAMPLE HOW IT COMES FROM FORM
<?
for ($i=0; $i < 9; $i++) {
?>
<input type="hidden" name="upload<?echo $i;?>" value="yes">
<?
}
?>

---

So this code is on the page the form calls

for ($i=0; $i < 9; $i++) {
echo $upload.$i; // THE VARIABLE NAMES ARE $upload0 - $upload8
}

Can I somehow use a counter variable (In this case $i) to change the variable name???

I only tried $upload.$i and $upload$i
I have no clue what else you could do??

Or do I have to code it like this

echo $upload0;
echo $upload1;
echo $upload2;
echo $upload3;
echo $upload4;
echo $upload5;
echo $upload6;
echo $upload7;
echo $upload8;

Also sorry for all the questions.. I am still a beginner trying to find my way....

Hello adamthenewbie the way your trying to echo out the correct varibles isn't working correctly because php is spitting out the contents of the varible $upload then + the contents of the varible $i so another way to do this so you could display all of your varibles is to loop through the post array
example
if your post array looks like this

$POST['upload1'];
$POST['upload2'];

foreach($_POST as $key => $value){
echo $value;
}

here the key varible will be upload1 or upload2 and the value varible will be the contents of those two varibles hope this helps

Use ${"upload" . $i}

Though frankly using an array may be better than using variable variables, unless you're also dealing with JS.
