Associative Array Values as keys for Associate Array

Hi there,

 

Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway)

 

My question is: is there a short-hand way to use a value from an associative array as the key in another associative array?

 

So for example, given this array:

 

$the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....);

 

then this kind of foreach loop doesn't work

 

$new_data = array();
foreach($the_array as $element){
$new_data[$element['name']] = $element['value']; 
}

 

Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it?

 

Cheers,

 

PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails.
