adding to the start of an associative array

[norpel]

how do I add an element to the start of an associative array.
eg. I want to add "zero"=>"zerovalue" onto the start of this

$oldarray = array("first"=>"firstvalue","second"=>"secondvalue");

I've tried array_unshift, but this makes the key for the first element 0.

surely this must be possible, but my googling isn't getting me too far.

I am not sure if there is a faster way than that, but you can say :

$oldarray = array("first"=>"firstvalue","second"=>"secondvalue");
$new_value = array("zero"=>"zerovalue");

$new_array = array_merge($new_values,$oldarray);

great... thanks, I knew it should be simple

You could use array_reverse() for this too. Not a great deal of difference unless the arrays are particularly large.
