== Why is this an issue?
|
|
|
|
In PHP, nested functions are functions, which are defined inside other functions.
|
|
They have access to the variables of the enclosing functions.
|
|
Once the parent function declares the nested function, the nested function becomes available to the global scope.
|
|
|
|
Code that uses nested functions can become difficult to read, refactor and to maintain and should therefore be avoided.

|
=== Noncompliant code example
|
|
|
|
With the default threshold of 3 level:
|
|
|
|
[source,php]
|
|
----
|
|
function f () {
|
|
function f_inner () {
|
|
function f_inner_inner() {
|
|
function f_inner_inner_inner() { // Noncompliant
|
|
}
|
|
}
|
|
}
|
|
}
