get_meta_tags - Extracts all meta tag content attributes from a file and returns an array

SYNOPSIS
       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.
