PHP - Merge two arrays (same-length) into one associative?

Question

Hi,

pretty straightforward question actually..

is it possible in PHP to combine two separate arrays of the same length to one associative array where the values of the first array are used as keys in the associative array?

I could ofcourse do this, but I'm looking for another (built-in) function, or more efficient solution..?

function Combine($array1, $array2) {
    if(count($array1) == count($array2)) {
        $assArray = array();
        for($i=0;$i<count($array1);$i++) {
            $assArray[$array1[$i]] = $array2[$i];
        }
        return $assArray;
    }
}

Answer 1

array_combine($keys, $values)

Answer 2

There’s already an array_combine function:

$combined = array_combine($keys, $values);

Answer 3

you need array_combine.

<?php
$a = array('green', 'red', 'yellow');
$b = array('avocado', 'apple', 'banana');
$c = array_combine($a, $b);

print_r($c);
?>
