Assign variable whilst checking it

Question

I'm not sure if this is even possible but I'm looking for a way to assign a variable whilst it's being checked in an if (...) { } statement. Basically something which makes this...

$var = somefunction();

if ($var == 10) {
    #do something
}

Into something like this

if(($var = somefunction()) == 10) {
    #do something
}

As I said im not sure if this is possible but just wondered if there was a way to save assigning the variable first. I'm wanting this because I have a function which either outputs an array or false.

Thanks :)

Answer 1

This will also work:

if(($var = somefunction()) == 10) {
    #do something
}

but the first way you proposed is simple, clear, and readable, aside from the fact that you need to use == or ===, not =, for equality checks:

$var = somefunction();

if ($var == 10) {
    #do something
}

Why wouldn't you just use that?
