It looks like you are using an assignment operator in your IF statement.
But you don't want to assign in your IF statement, you want to compare.
The single '=', will assign a value to a variable.
The double '==', will compare values. So try using the '==' in your IF statement.
Hope that helps!

2,188 Pointsso the first =, assigned the variable " " (null), then in the IF statement, did that variable then become assigned the integer 5, for the answer to come out that way?

6,187 PointsCorrect, the code within the condition of the IF statement reassigned the value of $a to 5.
So the computer sees IF ( 5 ) { echo "Hello ok, "; }, and 5 is a TRUE value in PHP.
