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.
The syntax of PHP echo is given below:
void echo ( string $arg1 [, string $... ] )
PHP echo statement can be used to print the string, multi-line strings, escaping characters, variable, array, etc. Some important points that you must know about the echo statement are:

- echo does not return any value.
- We can pass multiple strings separated by a comma (,) in echo.
