Well lets try.... <?php $OutputArray = array(); //Create an array to the output $fp = fopen ("yourgroupfile","r"); //Open the groupfile while ($d = fgetcsv ($fp, 1000, ":")) { //While loop as long there is some data $OutputArray[$d[2]] = $d[0]; //Set groupid as key, and groupname as value } //end of while fclose ($fp); //close file print_r($OutputArray); //Print out the array, to check the values! ?> Please reply if this doesn't work? By the way... if you got further problems, please tell us which version of PHP you use..... Regards, Johan Holst Nielsen www.weknowthewayout.com
