No need to set a time limit for this -- just set a limit on how far $sDate
can be decremented. Presumably only positive values are invalid, so just
stop the loop when $sDate goes <=0 -- either
for ($i = $Date; $i >= $sDate && $sDate > 0; $i--)
or something like:
for ($i = $Date; $i >= $sDate; $i--):
if ($Exists):
echo "Something here.";
else:
$sDate--;
if ($sDate<=0):
// do any necessary tidying up here -- e.g. set a
// flag to say the loop was exited via the side door
break; // escape from the for loop
endif;
endif;
endfor;
// break escapes to here
Cheers!
