Description:
------------
Hello,

on page http://php.net/manual/en/function.echo.php the syntax line "echo ( string $arg1 [, string $... ] ) : void" is incorrect.
As stated later echo is NOT a function.  If used with "(", a comma-separated argument list and ")", echo will fail (error message: [Thu Mar 21 18:41:34.397179 2019] [php7:emerg] [pid 5218] [client 192.168.0.33:62292] PHP Parse error:  syntax error, unexpected ',' in /var/www/html/album/now.php on line 9).
Please change the syntax-line to "echo string $arg1 [, string $... ]".

It took me some hours to find out the reason for the errors and to correct my php-scripts.

Thanks in advance
with kind regards

U. Geiß

Test script:
---------------
<!DOCTYPE html>
<html>
  <head>
    <title>Server clock</title>
  </head>
  <body>
<?php
  echo 'The server says: My clock shows "' , date( 'c' ) , '"' ;     // correct syntax
  echo( 'The server says: My clock shows "' , date( 'c' ) , '"' ) ;  // syntax as shown on http://php.net/manual/en/function.echo.php
?>
  </body>
</html>

Expected result:
----------------
The server says: My clock shows "2019-03-21T18:46:25+00:00" 

Actual result:
--------------

HTTP 500 error

The prototypes shown in the descriptions are not supposed to be valid PHP code.  How to interpret them is detailed in "How to read a function definition" [1] section of the manual.

[1] http://php.net/manual/en/about.prototypes.php

P.S. That page was slightly up to date, with regards to how we show return types.  The update page should be available online soon.
