If you have more values in a string, you can use array_walk() to create an new array instead of looping with foreach() or for(). I'm using an anonymous function which only works with PHP 5.3+.

// your string
$strVar = "key1 value1&key2 value2&key3 value3";

// new variable for output
$result = array();

// walk trough array, add results to $result
array_walk(explode('&', $strVar), function (&$value,$key) use (&$result) {
    list($k, $v) = explode(' ', $value);
    $result[$k] = $v;
});

// see output
print_r($result);

This gives:

Array
(
    [key1] => value1
    [key2] => value2
    [key3] => value3
)
