I've been working with PHP recently and I came across the concept of generators. From what I understand, generators are a really useful feature in PHP, but I'm a little confused about how they actually help with memory efficiency. I've read the documentation, but I'm still struggling to grasp the concept fully.
As much as I know, generators are functions that can be paused and resumed, allowing us to generate a sequence of values on the fly instead of generating them all at once and storing them in an array. This sounds great, but I'm not quite sure how it helps with memory efficiency.
Could someone please explain how generators specifically aid in improving memory efficiency in PHP? I would appreciate it if you could provide some examples or walk me through the process. Thanks in advance for your help!
