[SOLVED] Combining Arrays

[davidz]

I need to combine data from two arrays.  Specifically I need the values from one array and the keys from another combined where the keys are the same. 

Example:

[permissions] => Array
        (
            [ACPlatSearch] => 3
            [ACPropertySearch] => 11
            [ACActiveDwellings] => 12
            [ACUserInfo] => 13
            [ACStatsRecordedSubs] => 16
            [ACStats5yrTicker] => 17
            [ACStatsAbsorption] => 29
            [ACStatsTotalSales] => 28
            [ACStatsSalesProduct] => 27
            [ACStatsSalesDwellings] => 26
            [ACStatsSalesLots] => 25
        )

Plus:

Array
(
    [ACStatsSalesDwellings] => on
    [ACStatsRecordedSubs] => on
    [ACStats5yrTicker] => on
    [ACStatsActiveDwellings] => on
)

 

To end up like:

Array
(
    [ACStatsSalesDwellings] => 26
    [ACStatsRecordedSubs] => 16
    [ACStats5yrTicker] => 17
    [ACStatsActiveDwellings] => 12
)

 

Many thanks.

Not sure how well it will work with identical keys..

try using one of the array intersection functions:

Wow, thanks for the super fast replies.

 

I've tried different iterations of array_merge, array_intersec, array_diff, etc.  But I can only get it to show something like:

Array
(
    [0] => ACStatsSalesDwellings
    [1] => ACStatsRecordedSubs
    [2] => ACStats5yrTicker
    [3] => ACStatsActiveDwellings
)

 

Or the exact opposite of that.  My next option is to do a foreach.  Any thoughts?

Well, as far as i'm aware, a key cant be duplicated in an array - if thats part of the outcome that you wanted(im not 100% sure ) then it's not going to work.

try using the array_keys() and a counting function that get everything to line up nicely.

like

$keys = array_keys($array2);

while ($i <= $numkeys)

{

$array3[$keys[$i]] = $array1[$i];

$i++;

}

 

something like that

Thanks for all the input! Here is what I went with:

foreach ($_SESSION['permissions'] as $key1 => $value1){
     foreach ($new_permissions as $key2 => &$value2){
          if ($key1 == $key2){
	$value2 = $value1;
  }
     }
}

 

Thanks again!
