PHP echo() Function

PHP String Reference PHP String Reference

Example

Write some text to the output:

<?php
echo "Hello world!";
?>
Run example »

Definition and Usage

The echo() function outputs one or more strings.

Note: The echo() function is not actually a function, so you are not required to use parentheses with it. However, if you want to pass more than one parameter 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 shortcut syntax. Prior to PHP 5.4.0, this syntax only works with the short_open_tag configuration setting enabled.
