If - Else What?

[Michael J Alexander]

Mike Here

        Can someone tell me why this simple bit of code doesn't work? The "If" statement prints even when it's false.


$x = 20;
$y = 15.5;
$z = .05;
$a = $x+$y;

print "a equals $a.\n";

if ($a = 20) {print "a is equal to 20.\n";}

else {print "a is not equal to 20.\n";}
