Hi
This is my first question to these NGs, so please be gentle with me in any
replies :). I've crossposted it as I'm not sure which is the more appropriate
group.
I'm a relative newbie to PHP, and my Q in short is: is there an easy way to
manually change the arrangement of elements in an associative array?
I'll use an example from the PHP manual:
$a = array( 'color' => 'red',
'taste' => 'sweet',
'shape' => 'round',
'name' => 'apple',
);
If you then iterate through this with foreach() to print it out then the keys
and values will be printed in the order above. What I'd like to do is, say,
move $a['name'] up to 2nd place, so that it would print in the order:
'color'
'name'
'shape'
'name'
I don't want to sort the array, just rearrange it a bit. I've looked in the
array function list in TFM but can't see anything appropriate, and I couldn't
see anything on PX or phpbuilder.
The reason I want to do this is to arrange the values in a row extracted from
mySQL. If you click on any of the titles in my test database browse page at
http://www.nottingham.ac.uk/~ntzfr/rlos/database/rlo_titles.php you should get
a 'full record' page. The fields from "RLO No." down to "Record last updated"
are extracted from a single table 'RLO' with a simple SELECT query and their
names and values are stuck into the associative array $record. The fields below
(Author, Developer, etc) are extracted from junction tables by separate join
queries, and also assigned to $record. The table is then printed with a simple
foreach loop. What I'd like to do is shift, say, "Author" after "RLO title",
"Developer" after "Stage", and so on.
I could do this the clunky way, by manually assigning each key and value from
the queries into an array with the elements in the required order, and I'll do
that if there's no easy way of rearranging elements. I suppose I could use some
complex combination of shift(), pop(), merge() and whatnot, but that would
probably take up more time than the clunky way. TIA for any suggestions/tips.
