10 recommended articles about list()

Introduction: In PHP, the use of functions is still very flexible, but no matter what, functions, in the final analysis, are still a process.

Therefore, it cannot appear on the left side of the equal sign '='. This is the biggest difference between functions and language structures. For example, we often say: echo() and list() are a language structure, not a function, although they look like functions, because they can be placed on the left side of the equal sign and can accept assignment. But functions don't work. I hope this article will give you a deeper understanding of functions~~
