Finding a value in an array

Hi all, I am using fgetcsv() to get a tab delimited text file into an array. It gives me an array in this format: Array (

    [0] => Array
        (
            [0] => 97
            [1] => Effects of Slow Heating Rates on Products of Polyethylene Pyrolysis
        )

    [1] => Array
        (
            [0] => 103
            [1] => Effect of Heating Rate of Oxidative Degradation of Polymeric Materials
        )

    [2] => Array
        (
            [0] => 106
            [1] => Identification and Differentiation of Synthetic Polymers by Pyrolysis Capillary Gas Chromatography
        )

) From a form, I am passing in some values from checkboxes like: <input type="checkbox" name="notes[]" value="97" /> <input type="checkbox" name="notes[]" value="106" /> I need to be able to display the description string in the array for whichever checkboxes are checked. So for example if the user submits the form with the value "106" I want to display "Identification and Differentiation..." Any ideas? Please copy me on replies. Thanks, Rogue
