How to reindex filted Array

I would use array_walk and then array_filter then array_values to reset the index.

For example:

<?php
$array = [
    'radios1' => [
        'on'
    ],
    'from' => [
        '',
        'Bangalore',
        '',
        '',
    ]
];

array_walk($array, function (&$value, $key) {
    $value = array_values(array_filter($value));
});

print_r($array);

Result:

Array
(
    [radios1] => Array
        (
            [0] => on
        )

    [from] => Array
        (
            [0] => Bangalore
        )

)
