i have given two array here.

Array-1
        (
            [0] => 6
            [1] => 11
            [2] => 13
        )

        Array-2
        (
            [0] => 13.339066309
            [1] => 0
            [2] => 100
        )

I want to replace value of one array to key of another array. something like this:

Array
    (
        [6] => 13.339066309
        [11] => 0
        [13] => 100
    )

Use array_combine:

$new_array = array_combine($array1, $array2);

take a look at array_combine()

$result = array_combine(array_values($firstArr), array_values($secondArr));

Try this:

$result = array();

foreach ($array1 as $key => $value) {
    $result[$value] = $array2[$key];
}

Try something like this

$t = array();
$keys = array_keys($arr1);
for ($i = 0; $i < min(count($keys), count($arr2)); $i++) {
    $t[$keys[$i]] = $arr2[$i];
}
