Syntax for multiple switch statement to detect server environment [duplicate] - php

Question

Switch case with three parameters?
(7 answers)
Closed 8 years ago.
I need to detect different server environments in my site's config file. Up until now I was fine with detecting them using only the server's address.
switch ( $_SERVER['SERVER_ADDR']){
case '127.0.0.1':
// stuff
break;
case '111.222.333.444';
// stuff
break;
}
But I now need to test my environment against both the SERVER_ADDR and SERVER_NAME. I'm no php'er, so I've had a stab at
switch ( $_SERVER['SERVER_ADDR'] && $_SERVER['SERVER_NAME'] ){
case ('127.0.0.1','local'):
// stuff
break;
case ('111.222.333.444','gimmesomefunk.com');
// stuff
break;
}
But it's obviously wrong. Any clues?

If you want to keep using switch, you'll have to combine both to one variable like this:
switch (array($_SERVER['SERVER_ADDR'], $_SERVER['SERVER_NAME'])){
case array('127.0.0.1', 'local'):
// stuff
break;
case array('111.222.333.444', 'gimmesomefunk.com'):
// stuff
break;
}
However, the more normal way would be to use if, elseif:
if ( $_SERVER['SERVER_ADDR'] == '127.0.0.1' && $_SERVER['SERVER_NAME'] == 'local' ) {
// stuff
} elseif ( $_SERVER['SERVER_ADDR'] == '111.222.333.444' && $_SERVER['SERVER_NAME'] == 'gimmesomefunk.com' ) {
// stuff
}

I'm not sure it s the best method but you can concatenate values like this :
switch ( $_SERVER['SERVER_ADDR'].$_SERVER['SERVER_NAME'] ){
case ('127.0.0.1local');
// stuff
break;
case ('111.222.333.444gimmesomefunk.com');
// stuff
break;
}

You can't do this, as what you're actually entering the switch statement with is a boolean (true) because you're saying "is this string truthy, and this string truthy":
var_dump($_SERVER['SERVER_ADDR'] && $_SERVER['SERVER_NAME']) // bool(true)
You could simply do the following by using an if statement instead (you don't have to use $address and $name, but in my opinion it becomes more readable):
$address = $_SERVER['SERVER_ADDR'];
$name = $_SERVER['SERVER_NAME'];
if ($address === '127.0.0.1' && $name === 'local') {
// Stuff
} else if ($address === '111.222.333.444' && $name === 'gimmesomefunc.com') {
// Other stuff
}
