PHP function switch()

de switch() function works more or less like the if else structure. It takes an argument and depending of its value it will do something.


$var = 10;

if ( $var == 10 ) {
    echo 'Exactly 10';
} else {
    echo 'NOt 10';
} 
	

switch($var){
    case 10: 
        echo 'Exactly 10';
        break;
    default: 
        echo 'NOT 10';
        break;
}


switch($beer)
{
    case 'tuborg';
    case 'carlsberg';
    case 'stella';
    case 'heineken';
        echo 'Good choice';
        break;
    default;
        echo 'Please make a new selection...';
        break;
}

if ( $beer == 'tuborg' || 
     $beer == 'carlsberg' || 
     $beer == 'stella' || 
     $beer == 'heineken' ) {
    echo 'Good choice';
} else
    echo 'Please make a new selection...';
}
