How do i get the index key NOT the key string of an array?

[SM]

Hello,
I have an array that looks like the following one (see below). I need
to get the key index or position given a certain value.
So if the value is 22222222 the index/position in the array $cds[1] is
8. If XXXXXXXX the position is 4.

So my question is: how do i get the key index or position?
Thanks
Marco

$cds = array(
1=> array(
ClOHCQiD=> array('xxx', 'yyy'),
pZrhrRRX=> array('xxx', 'yyy'),
Lk3AGW6P=> array('xxx', 'yyy'),
XXXXXXXX=> array('xxx', 'yyy'),
t1knTITi=> array('xxx', 'yyy'),
yJd6OBlM=> array('xxx', 'yyy'),
J1tiIzSE=> array('xxx', 'yyy'),
22222222=> array('xxx', 'yyy')
)
);

I can't seem to think of anything too elegant right now, but you could
use a loop to create a new array with indexing starting from 1:

<?php

$cds = array(
1=> array(

'ClOHCQiD'=> array('xxx', 'yyy'),
'pZrhrRRX'=> array('xxx', 'yyy'),
'Lk3AGW6P'=> array('xxx', 'yyy'),
'XXXXXXXX'=> array('xxx', 'yyy'),
't1knTITi'=> array('xxx', 'yyy'),
'yJd6OBlM'=> array('xxx', 'yyy'),
'J1tiIzSE'=> array('xxx', 'yyy'),
'22222222'=> array('xxx', 'yyy')
)
);
$keys = array_keys($cds[1]);
$i = 0;
while ($i < sizeof($keys))
$keypos[$i+1] = $keys[$i++];

print_r($keypos);
?>

Just a note about the keys in your $cds hash, if you don't put quotes
around the keys (XXXXXXXX, t1knTITi, etc.), PHP will complain with
notices, since it thinks you're trying to use undefined constants.

Associative arrays do not have numeric keys so there's nothing you can
actually "get". You can, however, do many tricks. For instance:

index= array_search('XXXXXXXX', array_keys($cds[1]));
if($index!==FALSE){
$position = $index+1;
}

If your array keys are meaningless, why don't you simply use a numeric
array?

cds = array(
1=> array(
0 => array('ClOHCQiD', 'xxx', 'yyy'),
...
);

Or, even better, why don't you encapsulate all this logic in classes?

class Library{
public function addCD(CD $new_cd){
}
}

class CD{
public function addTrack(Track $new_track){
}
public function findTrack($track_id){
}
}

class Track{
}

Etc.

BTW, I can't believe you've defined constants for each key (apparently
random) key, so you're missing quotes around they keys and
error_reporting=E_ALL.
