Appending to variable name

digijohn

Hi, I am trying to write a for loop that adds to the end of a variable name an increment of 1. This way I can loop through x amount of items, and dynamically create the names (values are already being provided by HTTP_POST_VARS). What is the proper way to do this, if it is possible?

This is what I think it might look like:

for ($iteration = 1; $iteration <= $item_count; $iteration++) {
echo $item"$iteration";
}

for ($iteration = 1; $iteration <= $item_count; $iteration++) {
echo $item"$iteration";
}

where $item_count = the stopping point value?

that echo $item"iteration"; is going to kill it, bad syntax

the items are all labeled as follows:
$item1
$item2
$item3

Say there are 5 items, it would cycle through the loop 5 times, each time incrementing the number after "$item"($item1-$item5) by 1, until $item_count is reached. Does this make sense? Maybe there is a better way to accomplish this.

So you don't actually know the number of the items? $item_count should be an integer so if you dont know how many there are you need to first find out. Are these items in an array or?

$item_count will already have a value assigned to it. They are in an $HTTP_POST_VARS array, but variable tracking is enabled, so they can be accessed just by variable name. This is a post from the credit card gateway that I use, and the items that were purchased are labeled sequentially item1, item2 etc...

I'd still use an array, but: ${"item".$iteration}

${"item".$iteration}

OK, that was the little magic piece of code that I needed. concatenate! (he says slapping his forehead). Thanks a bunch guys.
