Connection format for PHP Echo string _php instance

First of all, let's say PHP echo () function

Definitions and usage

The Echo () function outputs one or more strings.

Note: the Echo () function is not actually a function, so you do not have to use parentheses over it. However, if you want to pass more than one argument to echo (), using parentheses will generate a parse error.

tip : the Echo () function is slightly faster than print ().

tip : the Echo () function also has shorthand syntax. Before PHP 5.4.0, this syntax only applies to situations where Short_open_tag configuration settings are enabled.
