Should I use an If or a Case or is there an easier way?

[denhamd2]

Hi,

I want to say if a variable begins with order196 or order197 or order198 or order199 order order200 then do something

Would anyone know some good code for doing this?

Why is your variable structure like that. Make it easy for yourself use an Array.

The only thing you can do here is use if/elseif/else

Basic programming question..

Use if/else when you know a few possible values for your variable, but cannot predict all possible values. For instance, say you're making a decision based on the length of a string:

In pseudocode..

if(string length ==0)
     do x;
else if(string length <10)
     do y;
else //string length is greater than 10
     do z;

Use th switch/case combination when you can reliably predict all possible values of a variable. And I mean no "greater thans","less thans", etc.. Only when you know every single value that your variable could possibly be.

switch($var){
     case 0
          do x;
     case 1
          do y;
     case 2
          do z;
     } //no other values of $var are possible
