Reset PHP Array Index

I have a PHP array that looks like this:

[3] => Hello
[7] => Moo
[45] => America

What PHP function makes this?

[0] => Hello
[1] => Moo
[2] => America

The array_values() function ^[docs] does that:

$a = array(
    3 => "Hello",
    7 => "Moo",
    45 => "America"
);
$b = array_values($a);
print_r($b);

Array
(
    [0] => Hello
    [1] => Moo
    [2] => America
)

If you want to reset the key count of the array for some reason;

$array1 = [
  [3]  => 'Hello',
  [7]  => 'Moo',
  [45] => 'America'
];
$array1 = array_merge($array1);
print_r($array1);

Output:

Array(
  [0] => 'Hello',
  [1] => 'Moo',
  [2] => 'America'
)

Use array_keys() function get keys of an array and array_values() function to get values of an array.

You want to get values of an array:

$array = array( 3 => "Hello", 7 => "Moo", 45 => "America" );

$arrayValues = array_values($array);// returns all values with indexes
echo '<pre>';
print_r($arrayValues);
echo '</pre>';

Output:

Array
(
    [0] => Hello
    [1] => Moo
    [2] => America
)

You want to get keys of an array:

$arrayKeys = array_keys($array);// returns all keys with indexes
    echo '<pre>';
    print_r($arrayKeys);
    echo '</pre>';

Output:

Array
(
    [0] => 3
    [1] => 7
    [2] => 45
)

you can use for more efficient way :

$a = [
    3 => "Hello",
    7 => "Moo",
    45 => "America"
];

$a = [...$a];
