echo

Name

echo — Sends string data to stdout.

Synopsis

void echo(data[, . . .]); mixed data: Data to be sent to stdout mixed . . . (optional): Additional arguments

Returns

Nothing.

Description

echo() is a language construct (as opposed to a function) that takes one or more arguments, converts them to a string, and sends them to stdout. Multiple arguments are separated with commas.

Note

echo() is slightly faster than print() .

Caution

Multiple arguments cannot be placed in brackets as with normal function calls. If this is done, a parse error occurs.

Version

PHP 3+

Example

Example 1199. Basic use of echo()

<pre>
<?php
// Use echo with a single argument
// Parentheses can be used
echo("Hello\n");

// Use echo with multiple arguments
// The arguments cannot be placed in parentheses
echo 'Hello', ' ', 'World', '!', "\n";
?>
</pre>
Output:
Hello
Hello World!
