You didnt provide any code. anyway, you can simply use $_GET global array to access the variables from your URL similalry use $_POST for post array. also you can just use 1 / true in the switch parenthesis like

switch(1) {

//use $_GET here to access your three vars
}

hope it will help

My button link is:

readers must understand that switch input section is like IF statement, if it gets any value other than 0 (which means false) it will execute its body..

so Tedd has shown you a method to get into the body of switch statement by passing true value to the switch input..

I have told you another use of switch input and that is to pass some values to it and then use it in the case making for example.

$name=”haroon”;
switch($name) {
case ($name == “tedd”):
echo “thanks for your supportive comments for all readers”;
break;
case ($name == “haroon”):
echo “thanks for your nice article ”;
break;
default:
echo “thanks for reading all these articles”;
}

for ($i = 0; $i < count($array); ++$i) {
    print $array[$i];
}

Two quick suggestions…

1) echo is faster than print.

2) “$i < count($array)” will recount the size of the array on each iteration, which will get exponentially worse the larger the array is that you’re working with. Instead, use:

for ($i = 0, $cnt = count($array); $i < $cnt; ++$i)

Otherwise, nice primer on arrays!

“the parenthesis of Switch accepts a value which is matched with cases and if any case if found true the block of code for that case is executed.”

My point was that you don’t need an input “variable” to be evaluated in the case statements that follow. For example,

switch(1)
{
case 1==2:
echo(”never);
break;

case 2==2:
echo(”always”);
break;

case 3==3:
echo(”never);
break;
}

The entire statement is based upon truth values.

of course you will need INPUT for switch statement otherwise you cannot reach switch cases… INPUT that is coming in the switch statment in fact initiate the switch statement block and cases are matched then like Caedes posted in his comment.

however programmers also send variables through INPUT and use them in CASE conditions.

The “input” portion of your switch statement can be used, or not. All case conditions are tested on their truth and not necessarily compared to “input”.

Try it, you’ll see that I am right.

PS: I’ve never used the ELSE-IF statement.

switch (true) {
case ($foo == $bar):
print($foo);
break;
case ($foo == 0):
print($bar);
break;
}

switch (true) {
case ($foo == $bar):
print($foo);

}
