PHP Echo () function

Instance

Output text:

<?phpecho "Hello world!";? >

Definition 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 on 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 a shorthand syntax. Before PHP 5.4.0, this syntax only applies when Short_open_tag configuration settings are enabled.
