    [0] => '1 Fail'
    [1] => '2 Fail'
    [2] => '3 Pass'
    [3] => '4 Pass'
    [4] => '5 Pass'
)

Array

    ['1 Fail'] => '1 Fail'
    ['2 Fail'] => '2 Fail'
    ['3 Pass'] => '3 Pass'
    ['4 Pass'] => '4 Pass'
    ['5 Pass'] => '5 Pass'

Is there a php function to convert from array 1 to array 2

PS: I know this so i am looking for a built in function

foreach($result as $value)
{
    $assoc[$value] = $value;
}

Answer 1

Assuming all your array values are unique:

$assoc = array_combine(array_values($arr), array_values($arr));
