echo $ABC =true;
else{

Why don't you tie the brackets? The Java language has to be bracketed in if.

Landlord Ah, single equals is assignment, not judge Ah
You assign a value of $ABC to 2, nonzero, true and else meaningless in if.
Echo should also be replaced by a double equal sign to determine whether it is equal
At this point the value of $ABC is 2 $abc = = True The result is 1

The first question is that you save the file in. php format!

$ABC = 4/2;
if ($abc = = 2)
echo $ABC = true;
Else
echo $abc = false;;
?>

if ($abc =2)
"=" is an assignment that is not a comparison


= Assignment = = Compare Content = = = Compare address and content

if ($abc =2) {//$ABC ==2
