Question

I have values passed c and 3 from $_GET variable, which I want to look up in an array as values and retrieve their keys. How can I search through the array to return accurate keys?

The code below

<?php

$array1 = array(0 => 'a', 1 => 'c', 2 => 'c');
$array2 = array(0 => '3', 1 => '2', 2 => '3');

$key1 = array_search('c', $array1);
$key2 = array_search('3', $array2);

?>

returns

$key1 = 1;
$key2 = 0;

though I am expecting

$key1 = 2;
$key2 = 2;

Answer 1

foreach ($array1 as $key => $value) {
    if ($value == 'c' && $array2[$key] == '3') {
        echo "The key you are looking for is $key";
        break;
    }
}

I’m pretty sure there’s a saner way to do whatever you’re trying to do though.
