PHP echo() function

Example

Output some text:

<?php echo "Hello world!"; ?>

Definition and usage

The echo() function outputs one or more strings.

Note: The echo() function is not actually a function, so you don't have to use parentheses around it. However, if you want to pass more than one argument to echo(), using parentheses will generate a parsing error.

Tip: The echo() function is slightly faster than print().

Tip: The echo() function also has simplified syntax. Prior to PHP 5.4.0, this syntax only worked when the short_open_tag configuration setting was enabled.
