Comments on: You can in fact use foreach to change array elements in PHP

Just want to correct Anon’s post:

When foreach first starts executing, the internal array pointer is automatically reset to the first element of the array. This means that you do not need to call reset() before a foreach loop.

Actually the original example works just fine. You need to unset the value after the loop: unset($value)

This is a good practice to follow, along with reseting your array before using it in a loop.

Have a good day.

I did a quick google to find out if I could use the foreach($array as $key=>value){..} to update arrays and this was the first thing that came up…

I’m traversing through a multi-dimensional JSON file as an array in PHP and one mistake would have had me spending hours fixing it!

Thankyou for saving me so much time!
