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.
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);
Array (  => audi  => benz  => ford )
