<para>
Opens <parameter>filename</parameter> and parses it line by line
for <meta> tags of the form
<example>
<title>Meta Tags Example</title>
<programlisting role="html">
<![CDATA[
<meta name="author" content="name">
<meta name="tags" content="php3 documentation">
</head> <!-- parsing stops here -->
]]>
</programlisting>
</example>
(pay attention to line endings - PHP uses a native function to
parse the input, so a Mac file won't work on Unix).
</para>
<para>
The value of the name property becomes the key, the value of the
content property becomes the value of the returned array, so you
can easily use standard array functions to traverse it or access
single values. Special characters in the value of the name
property are substituted with '_', the rest is converted to lower
case.
</para>
<para>
Setting <parameter>use_include_path</parameter> to 1 will result
in PHP trying to open the file along the standard include path.
</para>
