How to reset an array index in PHP

In this tutorial, we are going to learn about how to reset an array index in PHP.

Consider, that we are having the following PHP array with different indexes:

$cars = array(
 3 => "audi",
 4 => "benz",
 2 => "ford",
);

Now, we need to reset the above indexes numerically.

Resetting the array index

To reset the array index in PHP, we can use the built-in array_values() function in PHP.

The array_values() function takes the array as an argument and returns the array values with indexes numerically.

Here is an example:

$cars = array(
 3 => "audi",
 4 => "benz",
 2 => "ford",
);

$reset = array_values($cars);
print_r($reset);

Output:

Array
(
    [0] => audi
    [1] => benz
    [2] => ford
)
