Re: while() looping over query results twice?

OK, so I defined the variables before using them and that solved the problem. (Thanks!) I'm still curious as to why not defining them ahead of time would cause the data within each string to get duplicated. In other words, if the query results are "a,b,c,d", then by not defining the variable ahead of time produces "a,b,c,d,a,b,c,d" which is weird. At this point, my problem is solved, so this is more of an academic question than anything. Thanks for the help. --kurt On Thursday 25 October 2001 13:03, Jim Lucas wrote: > I notice that you are concatinating then each time. try setting them to > ="" before using them > > $companyID_string = ""; > $companyName_string = ""; > then: > while() > { > $companyID_string .= "," . $query_data[0]; > $companyName_string .= "," . $query_data[1]; > }
