PHP logical operators in IF statement

Question

I have this code:

if ( ($oldTime < (time() - self::wait)) ) {
  if ($this->setTime())
  {
    return true;
  }
  else
  {
    return false;
  }
} else {
  return false;
}

Can i replace it with:

if ( ($oTime < (time() - self::wait)) && $this->setTime() ) {
  return true;
} else {
  return false;
}

I need it to check if $this->setTime() returns true ONLY if $oTime < (time() - self::wait) is true.

So i can to the replacement right? and if $oTime < (time() - self::wait) is false, $this->setTime() will not be executed?

Yes, if I am understanding you correctly. && is a short-circuiting operator, so if the first condition is false, the second condition will not execute.

yes you can use this

if ( ($oTime < (time() - self::wait)) && $this->setTime() ) {
        return true;
    } else {
        return false;
    }

if first condition in the if statement with && ( not || ) fails, it will go to the else branch automatically without verifying the second condition
