I have code in php such as the following:\[code\]while($r = mysql_fetch_array($q)){// Do some stuff}\[/code\]where $q is a query retrieving a set of group members. However, certain groups have there members saved in memcached and that memcached value is stored in an array as $mem_entry. To run through that, I'd normally do the following\[code\]foreach($mem_entry as $k => $r){// Do some stuff}\[/code\]Here's the problem. I don't want to have two blocks of identical code (the //do some stuff section) nested in two different loops just because in one case I have to use mysql for the loop and the other memcached. Is there some way to toggle starting off the loop with the while or foreach? In other words, if $mem_entry has a non-blank value, the first line of the loop will be foreach($mem_entry as $k => $r), or if it's empty, the first line of the loop will be while($r = mysql_fetch_array($q))EditWell, pretty much a few seconds after I wrote this I ended up coming with the solution. Figure I'd leave this up for anyone else that might come upon this problem. I first set the value of $members to the memcached value. If that's blank, I run the mysql query and use a while loop to transfer all the records to an array called $members. I then initiate the loop using foreach($members as as $k => $r). Basically, I'm using a foreach loop everytime, but the value of $members is set differently based on whether or not a value for it exists in memcached.
