What does if ($var1 & $var2) mean in PHP?

The expression `if ($var1 & $var2)` in PHP is using the bitwise AND operator to check if both $var1 and $var2 have bits set to 1 at the same position. This means that the condition will evaluate to true only if both variables have corresponding bits set to 1. If you want to perform a logical AND operation on the values of $var1 and $var2, you should use the `&&` operator instead. 

if ($var1 && $var2) {
    // Code to execute if both $var1 and $var2 are true
}
