How to sort the position of a matrix automatically?

Question

Example, I have:

$matriz = array("Tomate", "Morango", "Melancia");

I would have:

(
    [0] => Tomate
    [1] => Morango
    [2] => Melancia
)

But if I do:

unset($matriz[0]);

I will have:

(     
        [1] => Morango
        [2] => Melancia
)

How to order automatically to return from 0

(     
        [0] => Morango
        [1] => Melancia
)

Answer 1

Just create the array again:

$newArray = array_values($oldArray);

Answer 2

You don’t necessarily need to create another variable, you can use it and override the values:

$matriz = array_values($matriz);

If you will always take only the first value of the array, the array_shift(), since it automatically reorders the array:

array_shift($matriz);
