Multidimensional arrays and grouping elements

[duckduckgoose]

I'm trying to create an array based on the values I retrieve.

I want to create arrays that looks like this:

$array = Array ( [id] => 54, [opts] => CKYM / YMLF / FATO )
$array = Array ( [id] => 34, [opts] => CKYM / PIMN )

But, I don't know how to set the key names when I explode the string.

foreach($subfoo["po"] as $option => $po){
     $names =  "$option,";
     foreach($po as $subpo) {
          $names .= $subpo["oa_value"]." / ";
     }
     $build = explode(",",substr($names.','.$cvalues,0,-3));
     echo '<pre>'; print_r($build); echo '</pre>';
}



//The above code outputs the following 2 arrays:
Array
(
    [0] => 54
    [1] => CKYM / YMLF / FATO 
)

Array
(
    [0] => 34
    [1] => CKYM / PIMN 
)

I have too much problem trying to reverse engineer your input data in order to do some troubleshooting so if you can post the input data $subfoo and $cvalues and then I will have a go on your problem.

What I did for simple testing was to:

$option = 54;
$po = Array('CKYM', 'YMLF', 'FATO');
foreach($po as $subpo) {
     $names .= $subpo." / ";
}
$build = Array("id" => $option, "opts" =>substr($names,0,-3));
echo '<pre>'; print_r($build); echo '</pre>';

which produced:

Array
(
    [id] => 54
    [opts] => CKYM / YMLF / FATO
)
