I don't think $$row[0] will give you anything good. as you're inside your while loop, $row should be declared, but the content of $row[0] depends on your request. you can check if $row[0] is set using "count $row"; but if you have an empty value in the first column, this will give you an empty string as result. try a print_r($row); after your "while". > // Declaring an empty array by the value of sales person code > $$row[0] = array(); > > I still don't understand why you're using $$row above. > // Current sales person code > $code = $row[0]; > > // Putting the product name as a key and the price as a value in the array > eval("\$code[\$row[1]] = \"$row[2]\";"); > do you really want to erase the content of $code you just set above with the eval statement ? $my_array = array(); $my_array[$1] = $2; > } > > } > > Thanks > > Could you please describe a bit more what you'd like to do/set, so we can give you a better help ? N F -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php The thing is that I want to name an array by the value in $row[0], sales person code. Once the array is declared it should not be declared again. The field never contains an empty value. After that I want to push in $row[1] as a key with $row[2] as a value, all related to the array name/sales person code. So if an array is declared that is equal as the value in the first field it should input a key and value. For example the array "AT" can contain 10 "collections" of data. Array ( [Product 1] => 1500 [Product 2] => 3000 [Product 3] => 500 ) etc, Hope I have made it a bit more easier to understand now. // Jonas -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
