How to write to the first element of an array?
I know reset can return the first element... but you can not use it to write to it.

sorry I was not clear... the array is not numeric... e.g $test['element_1']Mark– Mark2010-02-19 15:15:14 +00:00Commented Feb 19, 2010 at 15:15

The first question is similar... but its about accessing an array and not writing to it... the second is a completely different question...Mark– Mark2010-02-19 15:34:11 +00:00Commented Feb 19, 2010 at 15:34

Anything wrong with $yourarray[0] = $value ?
If you don't want to overwrite the first element, try "array_unshift":
http://www.php.net/manual/en/function.array-unshift.php
EDIT: ok, use this for non-numerical keys:
reset($yourarray);
$key = key($yourarray);
$yourarray[$key] = $newvalue;

That's called an "associative array" or a "hash". Technically, it doesn't have an order. You may have an item that you've put in first, but that's only incidental.

If it doesn't have an order, then why are there functions to sort it?
does this work?
reset($x);
$x[0] = $value;

The reset isn't actually needed to set the first element.
