Re: [PHP] mysql_free_result() question
Do I mysql_free_result the $Query or the $Result? If it's $Result, would this be the same as just going unset($Result)? mysql_free_result() frees the ressources that the MySQL server allocated for the results of your query. This is in the memory space of the MySQL server, while if you unset($Result), it only frees the MySQL result id (an integer if I remember corretly) in the memory space of your script. So, no, calling unset() is not the same to call mysql_free_result(). I could be wrong, and often am :-), but I believe that PHP4 knows about MySQL resources, and if you don't have any variables capable of accessing them any more (IE, you did unset($result)), then it's smart enough to do the mysql_free_result for you... This is, however, no excuse for you not writing less sloppy code in the first place, now that you are educated enough to know what you are doing. :-) Use mysql_free_result() if the memory de-allocation is important to you. -- WARNING [EMAIL PROTECTED] address is an endangered species -- Use [EMAIL PROTECTED] Wanna help me out?

Re: [PHP] mysql_free_result() question
You should call mysql_free_result($Query) !! It all becomes a little clearer if you change the names of the variables as such: $result = mysql_query(select ...); $row = mysql_fetch_assoc($result); That is, mysql_query() returns a result, and mysql_fetch_*() returns a row from such a result. Using mysql_free_result on a row is not advisable. Also, in my terminology, the query would be the string passed to mysql_query(), so you could do like this: $query = select ...; $result = mysql_query($query); $row = ... Regards, Jakob Kruse Chris Cameron [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I'm a bit unclear as to which result it is I use this function on. So lets say I; $Query = mysql_query(SELECT something FROM here); $Result = mysql_fetch_assoc($Query); Do I mysql_free_result the $Query or the $Result? If it's $Result, would this be the same as just going unset($Result)?
