Dynamically change a variables name

[Twey]

I edited it, I misunderstood you at first. Try this one.

There are also simple functions, like array_merge(), but I'm not sure that's customizable enough for your current purposes.

Not as far as I'm aware.

Tried it, still no luck.

Although I noticed that if the first value of $id is "100" and $qty is "6"

it will print
Array ( [0] => 600 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 )

Whereas if the first value of $id is "100" and $qty is "2"

it will print
Array ( [0] => 200 [1] => 0 )

Still looks like you're using the old code to me.

[jc_gmk]

oops, yeah I had both in there!

The new one is much better although it prints

Array ( [0] => 100 [1] => 100 [2] => 100 [3] => 100 [4] => 100 [5] => 100 )

Which is almost what i want but without the "[0] =>"

but instead the value just seperated with commas

Array ('100','100','100','100','100','100')

That's harder because PHP doesn't output that automatically.

function array_out($a) {
echo 'Array (\'';
echo implode('\',\'',$a);
echo '\')';
}

Do you know how i'd put that in relation to this: ?

$cart = array();
foreach($id as $k => $v)
for($i = 0; $i < $qty[$k]; ++$i)
$cart[] = $v; 

I'm assuming that i'd replace $a with $cart?
e.g.

function array_out($cart) {
echo 'Array (\'';
echo implode('\',\'',$cart);
echo '\')';
} 

[Twey]

Why are you printing an array like that? The string representation of an array is only meant for debugging purposes.

[djr33]

function name($argument) { ....stuff.... }

That creates a function.

For $cart, you'd use array_out($cart); and that would execute the commands in it.

Alternatively, you could just use the three lines from inside the function and replace $a in the second with $cart, as you did in the last code block (but then you don'tneed the first or last line)

[jc_gmk]

Perfect, thanks once again fellas!

My final code ended up like this:

$temp = array();
foreach($id as $k => $v)
for($i = 0; $i < $qty[$k]; ++$i)
$temp[] = $v;    

$cart = "array ('". implode("','",$temp)."')";

That confused me for a minute because it lacks brackets. I'd add them in for clarity.

foreach {
for {
...
}}
