用于检测服务器环境的多个switch语句的语法[重复]

Question

• Switch case with three parameters? 7 answers

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
}
