我可以基于数组做出if-else语句吗？

Question

Here is my current code:

if ( by == 'id') {
    handlePromises(identifier_websites)

} else if ( by == 'name'){
    handlePromises(names_websites)

} else if ( by == 'email' ) {
    handlePromises(email_websites)

} else if ( by == 'phone' ) {
    handlePromises(phone_websites)
}

Now I want to make it a little bit more modular (functional) . I mean, I want to make the whole code above based on an array like this:

$parts = ['id', 'name', 'email', 'phone'];

So if I add one item to that array, then automatically a else if block should be added to the code based on that item .

Is doing that possible?

Answer 1

Not sure if I get you but here's how you can automate the above slightly.

$parts = [ 
    'id' => identifier_websites, 
    'name' => names_websites, 
    'email' => emails_websites, 
    'phone' => phone_websites
];

foreach ($parts as $cond => $params) {
     if (by == $cond) { 
        handlePromises($params); 
        break; 
     }
}
