I've been working on a PHP project and I've run into a bit of a puzzling situation. I need to know if it's possible to create references to variables within functions or loops in PHP. I've been searching online but couldn't find a clear answer, so I thought I'd turn to this knowledgeable community for some guidance.
Let me give you some context regarding my specific situation. I have a function that iterates over an array using a foreach loop, and within this loop, I need to modify the values of the array elements. However, I want the changes to be reflected in the original array, not just within the scope of the loop.
I tried using references using the "&" symbol in the foreach loop, thinking that it would create a reference to the array element, but it doesn't seem to work as expected. The modifications I make within the loop do not affect the original array once the loop ends.
I'm wondering if there's a way to achieve what I'm trying to do. Is it possible to create references to variables within functions or loops in PHP? If not, are there any alternative solutions or workarounds that you can suggest?
I appreciate any help or insights you can provide on this matter. Thanks in advance!
