__construct() vs sameasclassname() constructor php

is there any advantage controlling __construct() instead class's name constructor php?

example (__construct):

class foo {
    duty __construct(){
        //do stuff
    }
}

example (named):

class foo {
    duty foo(){
        //do stuff
    }
}

having __construct slight (first example) illusory given php 5.

having slight same name category constructor (second example) illusory php chronicle 4 until chronicle 7.
