How to restart array keys?

Question

I have an array like this:

$arr = array("2"=>"red", "5"=>"blue", "3"=>"black", "12"=>"orange");

Now I need to rewrite all array items. So this is excepted output:

$newarr = array("0"=>"red", "1"=>"blue", "2"=>"black", "3"=>"orange");

Is doing that possible?

Answer 1

You can use array_values():

$newarr = array_values($arr);

Or just overwrite the previous variable with the new array:

$arr = array_values($arr);

Answer 2

just use the array_values function :

$newarr = array_values($arr);

Answer 3

You can try this to achieve expected result

$arr = array("2"=>"red", "5"=>"blue", "3"=>"black", "12"=>"orange");
$newarr = [];

foreach ($arr as $index => $value) {
    $newarr[] = $value;
}

Answer 4

$a = 0;
foreach ($arr as $i=>$value) {
$newwarr[$a] = $value;
$a++;
}
