php - Two compares in one if / else statement -

i trying find answer pretty simple question.

is possible ask 2 things in 1 if / else statement?

for example:

if($a>$b , isset($c))     return true;

i understand possible write like:

if ($a>$b) {  if (isset($c))     return true; }

i looking easier , less messy code. advises. thanks.

with of && operator :

if($a > $b && isset($c)){      return true; }

note: check both conditions true, if yes if block works. if want of them true lead if block execution go || operator.
