how to search array by specifying the index to start search from in php

Question

how to search array by specifying the index to start search from in php

for example: Assuming

$needle_to_search = 5;
$array_to_search = [6,8,4,9,7,5,9,4,5,9,3,5,4,6,7];
$index_to_start_search_from = 5;
$key = array_search($needle_to_search, $array_to_search, $index_to_start_search_from);

is there any function that can implement above pseudo code so that $key will return index: 8

what i mean is that i want to start the search from index 6 so that it returns index 8=> which has the value 5, since value 5 is my aim to search in the array.

Answer 1

i think you can do with array_slice .

$needle_to_search = 5;
$array_to_search = [6,8,4,9,7,5,9,4,5,9,3,5,4,6,7];
$index_to_start_search_from = 6;

// output

Array
(
    [0] => 6
    [1] => 8
    [2] => 4
    [3] => 9
    [4] => 7
    [5] => 5
    [6] => 9
    [7] => 4
    [8] => 5
    [9] => 9
    [10] => 3
    [11] => 5
    [12] => 4
    [13] => 6
    [14] => 7
)

// return 5
echo array_search($needle_to_search, $array_to_search);

// return 8
echo array_search($needle_to_search, array_slice($array_to_search, $index_to_start_search_from, null, true));
