RE: [PHP] Array Search Problem
Hi,
At the time when I am writing this, looks like I already got the functions I
needed. It turned out that I had to use some array_combine, sorting the items
by keys instead of values as well as using array_keys to get the values I
needed.
Thanks for pointing me towards the right direction.

Re: [PHP] Array Search Problem
(almost) all the tricks are in the comments of the help page for a
function, on php.net
but all functions accept only a given (and usually documented) set of
parameter(type)s, so you'll probably have to prepare the var, or even
call the function in a loop, outputting to yet another descriptively
named array that'll be used as "wanted list" later in the code.

Yes, I found a "recursive" way to find out the "index" like I wanted, by doing
something like
$from = explode("-", $from);
$state_colors= explode("-", $state_colors);
$change = explode("-",$change);
$count = count($new_array);
$i=0;
foreach ($new_array as $key => $value){
echo $i . " " . $key . " is " . $value . " miles away";
$i++;
}
You can see it is not very elegant, and plus, I created the $new_array so I
could do the ordering according to the values of the change array. I can tell
that since this is not a single array, which is probably why array_search does
not work.
Since I don't need the "value" of my "new_array" here, I am still finding out
how to "strip off" the values here without having to flatten my array. Is what
I am trying to do here possible? Or, is there a trick in array_search that I
could use to find the index without having to strip off anything?
Thanks for your help.
