PHP foreach loop key value

Question

You can access your array keys like so:

foreach ($array as $key => $value)

As Pekka stated above

foreach ($array as $key => $value)

Also you might want to try a recursive function

displayRecursiveResults($site);

function displayRecursiveResults($arrayObject) {
    foreach($arrayObject as $key=>$data) {
        if(is_array($data)) {
            displayRecursiveResults($data);
        } elseif(is_object($data)) {
            displayRecursiveResults($data);
        } else {
            echo "Key: ".$key." Data: ".$data."<br />";
        }
    }
}

You can also use array_keys() . Newbie friendly:

$keys = array_keys($arrayToWalk);
$arraySize = count($arrayToWalk); 

for($i=0; $i < $arraySize; $i++) {
    echo '<option value="' . $keys[$i] . '">' . $arrayToWalk[$keys[$i]] . '</option>';
}

foreach($shipmentarr as $index=>$val){    
    $additionalService = array();

    foreach($additionalService[$index] as $key => $value) {

        array_push($additionalService,$value);

    }
}
