php - Best practice for > < and == in a function -

-

i have come across conundrum use bunch of ifs or switch.

to put in perspective, current project working on involves comparing width , height of image number determine if width longer height or same.

here code far:

private function compare($width, $height) {     return $width - $height; }

this works might expect.

what find out if there better way this:

    if($this->compare($this->width, $this->height) == 0)     {      }     if($this->compare($this->width, $this->height) < 0)     {      }     if($this->compare($this->width, $this->height) > 0)     {      }

thanks

for value returned method compare(), have 3 posibilities, have 2 conditions , can obmit one:

$recievedvalue = $this->compare($this->width, $this->height); if( $recievedvalue == 0 ) {      // value equal 0 } else if( $recievedvalue < 0 ) {     // value less 0 } else {     // value more 0 }
