Example:

pippo.html
etc etc
<title>Il mio nome e' pippo</title>
<meta name="description" content"ciao ciao">
etc

pippo.php
$tags = get_meta_tags("pippo.html");
echo $tags['description'];

Case A) Failed
<title>Il mio nome e' pippo</title>
<meta name="description" content"ciao ciao">

echo $tags['description'], echos nothing

Case B) OK
<meta name="description" content"ciao ciao">
<title>Il mio nome e' pippo</title>

$tags['description'], echos ciao ciao


Case C) OK, I remove the character '
<title>Il mio nome est pippo</title>
<meta name="description" content"ciao ciao">

$tags['description'], echos ciao ciao

SUMMARY:
It seems there is a problem of get_meta_tags parsing the meta from an html file.
The problem is the ' character.
If it is contained inside a tag title before a meta then get_meta_tags fails.
If the title tag with the ' character is put after the meta, then it works.
If I delete the ' character then it works always.

Reopen if this happens with PHP 4.0.6

Yes, it happens with 4.0.6.

All your example html files are buggy:

<meta name="description" content"ciao ciao">

Note the missing '=' after content?

Sorry but when typing I forget a "=".
This html and php is pasted from the source directly:

test.html.............................................
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Questo e' un titolo di prova</title>
<META http-equiv=Content-Type content="text/html; charset=iso-8859-1">
<meta name="description" content="Il mio nome est pippo!">
<meta name="author" content="Andrea!">
</head>
<body>
</body>
</html>
end of file test.html.............................

pippo.php.....................................
<?php
$tags = get_meta_tags("test.html");
echo $tags['description']."<br>".$tags['author'];
?>
end of file pippo.php.........................

As I said:
This example (pippo.php) fails,
because it does not display the description and author tags correctly.
If I move the line <title> after the metas it works.
If I remove the character ' from <title> it works.

The file test.html has been validated at:
http://validator.w3.org
so the html code is correct.

Can't reproduce with latest CVS.
Please reopen if this doesn't work with
soon to be released PHP 4.1.0
