finding the negative value in an array php mysql

$variables = array(  'cf_12_1_08', 'cf_11_1_08',  'cf_10_1_08', &&..  'cf_1_1_00',);

There is one negative INT in the cf_ array.
I want to look into this array and name a new variable equal to the negative value.

In the second scenario, there are multiple negative vaules in the array and I want to create a variable that is equal to the array. For e.g. $negative_values (-10000, -1000 ,  ...  , -1000)

Thanks for the help,

Well, for the data in the array you have provided, I'm not sure how you are calculating what is negative or not? The format of the data, for example 'cf_12_1_08', appears to be some sort of non-standard data format. What are you considering a negative value?

If the values of the array are just integers, then you can use something like the following to add the negative values to a new array:
$negativeVariables = array();
foreach ($variables as $key => $value) {
     if ($value < 0) {
          $negativeVariables[] = $value;
}

'cf_12_1_08', 'cf_11_1_08',  'cf_10_1_08'
These are the names of the variables. For each of these INT, in a MYSQL database. there is a  negative or positive whole number.
I will try your suggestion and relpy shortly
thanks

Well, if you want to preserve the key names of the negative values, you should do this:
$negativeVariables = array();
foreach ($variables as $key => $value) {
     if ($value < 0) {
          $negativeVariables[$key] = $value;
}

I used the code you posted above. I made a mistake in saying the variables are INT. They are actually decimal(10,2)
For some reason the code echos the last value in the array 0.5, even when I change <0 to < -1
Any suggestions? Thanks again

First off, negative values are anything less than 0, not -1. So, you would use if ($value < 0.0)

Second, my code has no echo statements. I need to see how you are implementing it.
