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 echohow to make a print text in php
