Your if statements are assigning values. Not comparing...to compare you need to use == , not just =. With your current statements, each if statement will always be true, just the value of $a changes at each if. <? $a="null"; if ($a=="dwa") { // one sign = so it is OK echo "OK"; } if ($a==true) { echo "OK"; } if ($a==false) { echo "OK"; //but it is not written!!!!!!! } ?> Is what you need. Also for me boolean checks in my opinion are much simplier if you use 1-0 for the comparison (but use what you need, I don't know your entire code). Sincerely, Craig Vincent
