How does recursion work in PHP?

PHP also supports recursive function call like C/C++. In such case, we call current function within function. It is also known as recursion. It is recommended to avoid recursive function call over 200 recursion level because it may smash the stack and may cause the termination of script.

Does PHP have recursion?

Anonymous recursive function is a type of recursion in which function does not explicitly call another function by name. This can be done either comprehensively, by using a higher order function passing in a function as an argument and calling that function.

What is the full form of PHP?

It is especially good for working on things that have many possible branches and are too complex for an iterative approach. One good example of this would be searching through a file system.

How recursion is helpful in programming?

Recursive thinking is really important in programming. It helps you break down bit problems into smaller ones. Often, the recursive solution can be simpler to read than the iterative one.
