Question

I have a string that looks like: key1/value1/key2/value2/ and so on

I did an explode('/',trim($mystring,'/')) on that

Now I want to haven an associative array like:

array(
 'key1' => 'value1',
 'key2' => 'value2',
  ...
);

of course i can do it with an for loop where i always read two entries and push them into a target array, but isnt there something more efficient and elegant? a one liner with some some php core function similar to ·list()· or something?

A method using array_walk() with a callback function:

function buildNewArray($value, $key, &$newArray) {
    (($key % 2) == 0) ? $newArray[$value] = '' : $newArray[end(array_keys($newArray))] = $value;
}

$myString = 'key1/value1/key2/value2/';
$myArray = explode('/',trim($myString,'/'));

$newArray = array();
array_walk($myArray, 'buildNewArray', &$newArray);

var_dump($newArray);
