1. echo Statement
* we can write echo statement with parenthesis like 'echo()' or without parenthesis 'echo'.
* In the echo we can pass multiple variable in comma separated form to see the output like 'echo $a,$b,$c;'
* echo doesn’t return any value
* echo is faster then print

2. Print Statement
* we can write print statement with parenthesis like 'print()' or without parenthesis 'print'.
* In the print we can not pass multiple variable in comma separated form like echo.
* print statement always returns 1.
* print is slower than echo

Example 2: echo php

<?php 
$string = "Hello, World!";
echo $string;
?>
