Eregi() to extract author meta tag?

[Jane Doe]

Hi

I took a quick look in the archives, but didn't find an answer
to this one.

I'd like to display a list of HTML files in a directory, showing the
author's name between brackets after the file name. I can successfully
extract the TITLE section, but no luck with the AUTHOR part. Any idea
why?

<?php
$body = "<h1>Docume nts</h1>";

$dir = opendir(".");
while ($item = readdir($dir)) {
//Only HTM(L) files
if(substr($item ,-5) == ".html" || substr($item,-4) == ".htm") {
$fp = fopen($item, "r");
$contents = fread($fp, filesize($item) );
fclose($fp);

//Works OK to extract TITLE
eregi("<title>( .+)</title>", $contents, $regs);
$file[$item] = $regs[1];

//Doesn't work
//eregi("<meta name=\"author\" content=\"(.+)\ ">', $contents,
$regs);

//Doesn't work
eregi('<meta name="author" content="(.+)"> ', $contents, $regs);
If ($regs[1])
$author[$item] = "(Author unknown)";
else
$author[$item] = "(" . $regs[1] . ")";
}
}

$body .= "<ul>\n";
foreach ($file as $item => $title) {
$body .= "<li><a href=\"" . $item . "\">" . $file[$item] . "</a> " .
$author[$item];
}
$body .= "</ul>\n";

print $body;

?>

FWIW, I tried making eregi non-greedy using (.+?) or ([^"].+), and
also used double quotes (shown above), all to no avail.

Any tip much appreciated.

Thank you
JD.

Consider get_meta_tags.

http://www.php.net/manual/en/function.get-meta-tags.php

And remember there's no requirement for an author to (a) show her
real name; or (b) use the so-called "author" meta tag, or any meta
tag for that matter.

Thx John :-)

BTW, is there a similar API to extract the title section? It's kinda
stupide to have PHP parse the same document twice to extra this and
the meta tags:

$fp = fopen($item, "r");
$contents = fread($fp, filesize($item) );
fclose($fp);
eregi("<title>( .+)</title>", $contents, $regs);
if (!$regs[1]) {
$title = "(Title not filled)";
} else {
$title = $regs[1];
}

$tags = get_meta_tags($ item);

if (!$tags['author']) {
$author = "(Author not filed)";
} else {
$author = "(" . $tags['author'] .")";
}
print "<li><a href=\"$item\"> $title</a> $author";

It's OK. I run a script prior to accepting a document inside our CMS,
and reject any document that doesn't have the TITLE and AUTHOR
sections filled.

Stupid me :-) Just use the "descriptio n" meta tag, and be done with
it.

Thx again

Let me start with the obvious, but rather dumb, question: are you
sure that the tags are there? If they are, recall that PHP has
a function that does exactly what you want:

http://www.php.net/get_meta_tags

Yes, since I'm the one proofreading docs before uploading them :-)
