[seamuslee001]

…m as per example #1 at http://php.net/manual/en/function.each.php

Overview

This removes the usage of the each() function. The each function is different to foreach in general except when used in a while (list(x, y) = each(blah)) situation. Here i have tried to replicate the output of what each would be as per Example #1 here http://php.net/manual/en/function.each.php specifically the first of the 2 examples in Example #1

Before

Deprecated function used

After

no depreciated function used

@seamuslee001 I think your analasys if how each() is used is correct, however, looking at the way the variable is used in this function, I think it wasn't needed at all. See #12210
