Split a delimited string into a key-value pair

How do I implode 2 values, 1 as the key and the other as the value. Say I have:

$string = 'hello_world';

$arg = explode('_', $string);

I now have $arg[0] and $arg[1] (as you know)

How can I implode that so it becomes this structure

Array (
    'hello' => 'world'
)

Here's a fun way to do it without using intermediate args ;)

$string = "hello_world";
$result = call_user_func_array( "array_combine", array_chunk( explode("_", $string ), 1 ));

$string = 'hello_world';
$arg = explode('_', $string);
$array = array($arg[0] => $arg[1]);

would be the quickest way

I'm not sure if you're looking for something this obvious:

$arg = explode('_', 'hello_world');
print_r(array($arg[0] => $arg[1]));

I assume it's a bit more complicated than this. Maybe the string contains multiple of these things. ex: 'hello_world,foo_bar,stack_overflow'. In which case you'd need to explode by the comma first:

$args = explode(',', 'hello_world,foo_bar,stack_overflow');
$parsed = array();

foreach($args as $arg) {
    list($key, $value) = explode('_', $arg);
    $parsed[$key] = $value;
}
