remove element from array and reindex from 0

Question

Array (
    [REF_DETAILS] = Array
        (
            [0] = Array
                (
                    [ID] =&gt; 1231312
                    [USER] =&gt; USER
                )

            [1] = Array
                (
                    [TID] =&gt; 2754042         
                    [USER] = USER
                )
            [1] = Array
                (
                    [TID] =&gt; 534535         
                    [USER] = USER
                )

        )

    [TOTAL_COUNT] = 31
)

I have a array output like this above and I want to remove one element from the array then again i want to reindex it from 0. I tried with array_value in php but after doing this it is removing [REF_DETAIL] with 0 and TOTAL_COUNT as 1 , please provide the solution in php

The sample data is impossible. Duplicate keys may not exist on a single level in an array. — mickmackusa, Oct 05 '20 at 01:32

Use array_splice (php docs), it automatically reindexes.

array_splice($array['REF_DETAILS'], 1, 1)

try

unset($array['REF_DETAILS'][1]);
$array['REF_DETAILS'] = array_values($array['REF_DETAILS']);

very expensive solution if the arrays get bigger. – Andreas Grapentin Sep 01 '12 at 07:46

Use array_shift

$arr = Array (
    'REF_DETAILS' => Array(
        0 => Array(
            'ID' => '&gt; 1231312',
            'USER' => '&gt; USER',
        ),
        1 => Array(
            'TID' => '&gt; 2754042         ',
            'USER' => 'USER',
        ),
        2 => Array(
            'TID' => '&gt; 534535         ',
            'USER' => 'USER',
        ),
    ),
    'TOTAL_COUNT' => 31,
);

array_shift($arr['REF_DETAILS']);
print_r($arr);

output:

Array
(
    [REF_DETAILS] => Array
        (
            [0] => Array
                (
                    [TID] => &gt; 2754042
                    [USER] => USER
                )

            [1] => Array
                (
                    [TID] => &gt; 534535
                    [USER] => USER
                )

        )

    [TOTAL_COUNT] => 31
)

remove element from array and reindex from 0
