PHP代码应该在运算符之前有空格吗？

Question

I've seen a lot of code recently formatted as the following:

A:

if ($var=='test'){
    $var=Foo('blah'.$var1);
}else{
    // do something
}

Personally I don't like it and would prefer it as:

B:

if ($var == 'test') {
    $var = Foo('blah' . $var1);
} else {
    // do something
}

I think it's much more readable (note the addition of spaces).

Is there a general preference in the community or is one way better than another?

Answer 1

The most important thing is to follow a standard and stick to it.

That said maybe you can follow Zend's Framework standards and they use spaces. Check C.4.6.

if ($a != 2) {
    $a = 2;
}

Hope it helps!
