Question

I have just a question… I’m seeing this coding style in various php scripts and don’t understand what this means… Could someone explain me this^^

example code:

empty($config) OR $this->initialize($config);

or this

$url AND $this->create($url);

Answer 1

That about the OR operator : if 1st condition is true, then PHP won’t bother to execute 2nd: knowing that the 1st is true is enough to return true.

You can do the same for and (except it’s the opposite of course: if 1st condition is false, PHP won’t interpret 2nd)

This

empty($config) OR $this->initialize($config);

Is a shortcut for

if ( ! empty($config)) { //(BTW I guess it should be if (empty($options)) no? )
    $this->initialize($config);
}

And

$url AND $this->create($url);

for

if ( ! $url) {
    $this->create($url);
