I have variables being passed to me via a Post operation.
They have names like: $data_XX
Where XX are contents of an array of known size.
ie:
$array=(12, 43, 23, 22);
$data_12 = "some content"
$data_43= "some other content"
How can i write code to access these data_XX elements if the XX parts are known only at runtime?
I hope this makes sense.
Thank you for any help

That should contain everything you'll need.
Also, you can submit entire arrays with forms, and PHP will interpret it.
IE:
<input type="text" name="var[0]" value="data">
<input type="text" name="var[1]" value="data2">
will be treated like the following upon submission:
$var = array("data", "data2");
I've even used it for two dimensional arrays, and associative arrays (name="var[subvar][0]").
This can come in handy.
