Description:
------------
According to this page:

http://www.php.net/manual/en/function.main.php

the misbehaviour was stopped in PHP 4.3.2, however it is still present in the latest 5.1.x snapshot.

In addition when require_once() or include_once() call fails and "html_errors" is "On" the error message HTML link points to the same function "require()" or "include()", without the _once() part in it.

A sample script:

<?php
require_once('nonexisting');
?>

Produces this HTML (html_errors=on):

<b>Warning</b>:  main(fake) [<a href='http://www.php.net/manual/en/function.main.php'>function.main.php</a>]: failed to open stream: No such file or directory in <b>x.php</b> on line <b>2</b><br />
</span>

<b>Fatal error</b>:  main() [<a href='http://www.php.net/manual/en/function.require.php'>function.require.php</a>]: Failed opening required 'fake' (include_path='.:/usr/lib/php') in <b>x.php</b> on line <b>2</b><br />


This illustrates both points:  the erroneous main() function as well as the wrong html link  (should be funtion.require-once.php)

Sorry, the script above should have

require_once('fake');

The docs are wrong - I can see the same problem in 4.3.6 and 4.3.10.
Also, I don't see an easy way to fix it, since include_*()/require_*() aren't really functions, but language constructs.

I removed the "No longer points here" column from function.main in CVS.

This is maybe not easy to fix but it's still a bug:

1. Prior to function.require error message, there's a bogus function.main error message - it should be silented.

2. require_once() points to function.require and not function.require-once, include_once() parallel.

Fixed in CVS HEAD and PHP_5_1.
