RE: [PHP] How do I make an array like this?

Ok, I went back and read your original problem. You are making things much more complex than they really are. This will do the trick: $fp = fopen('WallCost.csv','r'); while(!feof($fp)) { $arr = fgetcsv($fp,256); $WallCab[$arr[0]] = array(1=>$arr[1],2=>$arr[2]); } fclose($fp); That's all. It is fast, doesn't eat up a bunch of memory by loading the entire file into RAM, and doesn't need to split up each line. -Rasmus On Tue, 11 Jul 2000, Ted Knudson wrote: > Thanks > > That worked up to a point but I still do not know how to get the result I > want. > This is the code I wrote from your description but I need some help at the > end of the code. > > <?php > $Lines = file("WallCost.csv"); > > for ($i =0; $i < count($Lines); $i++) > { > // print $Lines[$i]."<br>"; //Works OK! > List($key, $cost, $thickness) = split(",", $Lines[$i]); > Print $key."
