Hello,

I was wondering if it is possible to build up a switch() routine dynamically, based on how many elements there are in an array.

So if there are 3 elements in this array, my switch would need to look like:

PHP Code:

switch ($variable) {
case 1:
//do stuff
break;

case 2:
//do stuff
break;

case 3:
//do stuff
break;

default:
//do stuff
break;
} 


Or, if there are 2 elements in this array, my switch would need to look like:

PHP Code:

switch ($variable) {
case 1:
//do stuff
break;

case 2:
 //do stuff
 break;

default:
 //do stuff
 break;
} 


Is this somehow possible?

thanks!

Matt

Can you give some background on what you're trying to do? :-)

You might be able to hack something like that together using eval() but I don't recommend it. Is there any reason you can't use a loop:

PHP Code:

for($i = 0; $i < $arraySize; $i++)
{
     if($variable == $i)
     {
          //do stuff
     }
} 


More details might yeild a better answer.

Matt's code is suggesting a question: What is the "stuff" you want to do? Very likely, if you are trying to do a dynamic switch, you have something off in how you're thinking about the problem. Try presenting us with the problem you're solving with this switch and we can look at suggesting an alternative solution.
