Question

I’m trying to come up with a way combine two arrays that have different key names with identical values? The order of that the matching values may differ, so it would need to check if it’s a match and then merge if yes. Is there an easy way to accomplish? Any help or guidance is appreciated.

Array 1

Array
(
[0] => Array
    (
        [location_id] => 1
        [location_title] => Centralia
        [location_slug] => Centralia
        [state_name] => Illinois
    )

[1] => Array
    (
        [location_id] => 3
        [location_title] => Columbia
        [location_slug] => columbia
        [state_name] => Illinois
    )

[2] => Array
    (
        [location_id] => 15
        [location_title] => Dixon Hennepin
        [location_slug] => dixon-hennepin
        [state_name] => Illinois
    )
)

Array 2

Array
(
[0] => Array
    (
        [hours_locationid] => 3
    )

[1] => Array
    (
        [hours_locationid] => 1
    )

[2] => Array
    (
        [hours_locationid] => 15
    )
)

Try this below,

replace $array1 and $array2 -> demo : http://codepad.org/1inDuoVe

<?php
$array1 = array(array("a"=>"aaa","b"=>"bbb"),array("x"=>"xxx","y"=>"yyy"));
$array2= array(array("c"=>"ccc"),array("z"=>"zzz"));
$i=0;
$j=0;
foreach($array2 as $single){
    foreach($array1 as $multiple){
        if($i == $j){
            $keys = array_keys($single);

            print $key = $keys[0];
            $multiple = array_push_assoc($multiple,$key,$single[$key]);
            $array1[$j] = $multiple;
        }
        ++$j;
    }
    ++$i;
}

var_dump($array1);

function array_push_assoc($array, $key, $value){
$array[$key] = $value;
return $array;
}
?>
