Php code

Question

How is it possible I don’t know????
$a =1;
echo $a++;
echo ++$a;

Answer 1

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.

Answer 2

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
