get_meta_tags
GET_META_TAGS(3) 1 GET_META_TAGS(3)get_meta_tags - Extracts all meta tag content attributes from a file and returns an arraySYNOPSIS
array get_meta_tags (string $filename, [bool $use_include_path = false])
DESCRIPTION
Opens $filename and parses it line by line for <meta> tags in the file. The parsing stops at </head>.
PARAMETERS
o $filename
- The path to the HTML file, as a string. This can be a local file or an URL.
Example #1
What get_meta_tags(3) parses
<meta name="author" content="name">
<meta name="keywords" content="php documentation">
<meta name="DESCRIPTION" content="a php manual">
<meta name="geo.position" content="49.33;-86.59">
</head> <!-- parsing stops here -->
(pay attention to line endings - PHP uses a native function to parse the input, so a Mac file won't work on Unix).
o $use_include_path
- 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.
RETURN VALUES
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 eas-
ily use standard array functions to traverse it or access single values. Special characters in the value of the name property are substi-
tuted with '_', the rest is converted to lower case. If two meta tags have the same name, only the last one is returned.
EXAMPLES
Example #2
What get_meta_tags(3) returns
<?php
// 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
?>
NOTES
Note
Only meta tags with name attributes will be parsed. Quotes are not required.
