PHP Tutorial Part 3 : PHP Echo

PHP Echo

PHP echo is a language construct, not a function. Therefore, you don't need to use parenthesis with it. But if you want to use more than one parameter, it is required to use parenthesis.

void echo ( string $arg1 [, string $... ] )

• echo does not return any value.
