Unsetting elements of array in a for loop in php

Posted May 27th, 2011 in Snippets by Metod

I did something like this today:


The loop never came to the final element of the array, therefore not checking all of them. What was the problem?

Since sizeof($arr) is calculated every time the loop comes around, it was returning less and less with every unset instead of returning the same value.

Solution:


That way you ensure that size is always the correct integer. And it will run faster.

At the moment I am doing some java programming. And since being primarily a php guy, I was wondering how to easily return an array from a method like you can in php:

public function returnArray() {
    return array(1, 2, 3);
}

And I found a way which is quite nice:

public int[] returnArray() {
    return new int[]{1, 2, 3};
}
