Here's an example of a simple generator function in PHP:To use this generator, you can use a foreach loop like this:This would output the numbers from 1 to 10, one per line.Generators have several advantages over regular functions. For one, they are more memory efficient because they only generate and return one value at a time, rather than creating an entire array of values up front. This can be particularly useful when working with large datasets that would otherwise consume a lot of memory.Generators are also easier to write and read than other iterable data structures like arrays or objects, which can make them a more convenient choice in certain situations.
