PHP fgets() strict !== operator

I saw the code below in the PHP Documentation for fgets():

while (($buffer = fgets($handle, 4096)) !== false) {
        echo $buffer;
    }

My question is: why is there a strict !== ?

Why can't you just do:

 while ( $buffer = fgets($handle, 4096) ) {
            echo $buffer;
        }
