Hi ppl, I have a problem on programming, Iam trying to create a function that can check whether a number is 0 1 2 6 7 8 12 13 14 18 19 20 24 25 26 the function will just return true if the number is one of the above but without mentioning the numbers staticly meaning not like this: if( $num==0 && $num==1 && $num==2 && $num==6 ..and so on ) but something like this: function progression( $num, $diffBetween ) { if( $num%2 ) return true ; else return false ; } can anyone help?.... thanks in advance PHP Data object relational mapping generator http://www.metastorage.net/ Yahoo!
