Re: using integers as array keys

Alex, I was curious how that would work, so I wrote the following script (using php4) function echoIsSet($sub) { global $myarray; if(isset($myarray[$sub])) echo "$sub is set<BR>"; else echo "$sub is NOT set<BR>"; } $myarray=array(); $myarray[567]=1; $myarray[31416]=1; echoIsSet(0); echoIsSet(1); echoIsSet(567); echoIsSet(1000); echoIsSet(31416); echoIsSet(40000); with the following results. 0 is NOT set 1 is NOT set 567 is set 1000 is NOT set 31416 is set 40000 is NOT set This isn't what you want?
