The first echo prints 1 The second echo prints 3. He may be talking about the second echo. You can ask him again. You can refer the above answer id you have doubt about how 1 came.

First of all, you have to write the code inside the below block <?php ?> If you don't write the code within this, it will be taken as normal text. If you have any problem with logic then the below answer may be helpful. $a = 1 means variable a is assigned the value 1. echo $a++ means the post increment operator is used with variable a. In post-increment, the variable a is printed first then the value of a is incremented by 1. So the output will be 1 and value of a at that time will be 2. echo ++$a means pre-increment operator is used with variable a. So first value of a is incremented by 1 and then it is printed. So value of a after incrementing is 3 and 3 is printed
