get_meta_tags

(PHP 3 >= 3.0.4, PHP 4, PHP 5)

Opens filename and parses it line by line for
<meta> tags in the file. The parsing stops at
</head>.

The path to the HTML file, as a string. This can be a local file or an
URL.

Example 1. What get_meta_tags() parses

Setting use_include_path to TRUE will result
in PHP trying to open the file along the standard include path as per
the include_path directive.
This is used for local files, not URLs.

Returns an array with all the parsed meta tags.

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. If two meta tags have the same
name, only the last one is returned.

Example 2. What get_meta_tags() returns

// Assuming the above tags are at www.example.com
$tags = get_meta_tags('http://www.example.com/');
 
// Notice how the keys are all lowercase now, and
// how . was replaced by _ in the key.
echo $tags['author'];       // name
echo $tags['keywords'];     // php documentation
echo $tags['description'];  // a php manual
echo $tags['geo_position']; // 49.33;-86.59
