Finding values in an array using criteria - php and mysql

$variables = array(  'cf_12_1_08'=>1,
       'cf_11_1_08'=>2,
                   'cf_10_1_08'=>3,
&&..
                   'cf_1_1_00'=>108,
);
There is one negative INT in the cf_ array.
I want to look into this array and get the value (1,2 &. 108) associated with the negative INT.
I tried this but have been unable to make it work.
foreach ($variables as $letter=>$number) {
if ($query[$letter] < 0) $negative_id = $number;
}
I think it is just a minor code adjustment
At the moment with the code above, the script results in 108
Thanks for the help,

I don't understand where your negative INT's are? You have some sort of string acting as a key, and then an INT value paired with it. You are saying you want to retrieve 1, 2, and 108 for the negative VALUE. This doesn't make sense.

The negative value is the value associtated with one of the variables cf_. I want to look into the array and find the negative value, then echo the number associated with that value. For e.g. if the value of 'cf_10_1_08' = -10000, then the new variable would be 3.
I also messed up with the original question. The variable should have a $. For e.g. '$cf_10_1_08' = -10000
Sorry for the confusion

You can't have duplicate keys in an array, so you can't have 'cf_10_1_08' = -10000 and 'cf_10_1_08' = 3. I'm still unclear as to what you are exactly attempting to do.

It sounds like you have an array with key/value pairs, and if a value is negative, you want to return the key associated with it. Is this correct?
