In PHP 4, any function with the same name as the nesting class was considered a class constructor. In PHP 5, this mechanism has been deprecated and the "__construct" method name should be used instead. If both styles are present in the same class, PHP 5 will treat the function named "__construct" as the class constructor.

This rule rule raises an issue for each method with the same name as the enclosing class.

Noncompliant Code Example

class Foo {
  function Foo(){...}
}

Compliant Solution

class Foo {
  function __construct(){...}
}
