    Hi ,
    I would like to fetch the meta decription and keyword of many sites .I have a script to do it.While doing so
    I have come across three different meta tag structure :
    1. <meta xmlns="http://wwww.w3.org/1999/xhtml" name="description" content="meta decription goes here" />
    2.<meta name="description" content="meta decription goes here" />
    3.<meta http-equiv="description" content="meta decription goes here" />

    How to fetch the description.Due to this difference in structure i am unable to fetch the details and as well us i need to know is there any other type other than the above three.
    FYI:Same goes to meta keywords.

    Have anybody faced this problem?
    Do you have any solution or suggestion.
    Please advice me.
    Cheers.

    Here is the PHP code i made for you:
    
<?php
$site=file_get_contents("http://aioshared.com");
$head=explode("<head>",$site);
$head=explode("</head>",$head[1]);
$head=$head[0];
$desc=explode('name="description"',$head);
$desc=explode("content=",$desc[1]);
$desc=explode(">",$desc[1]);
$arr=array('"','/');
$description=str_ireplace($arr,"",$desc[0]);
if ($description==""){
$description="Can't Fetch Description";
}

$keyw=explode('name="keywords"',$head);
$keyw=explode("content=",$keyw[1]);
$keyw=explode(">",$keyw[1]);
$arr=array('"','/');
$keywords=str_ireplace($arr,"",$keyw[0]);
if ($keywords==""){
$keywords="Can't Fetch Keywords";
}

echo "<b>Description:</b>".$description."<br>";
echo "<b>Keywords:</b>".$keywords."<br>";
?>
    PHP:
    If you face any problem with it, then let me know :)

    Thanks!

    #3 is just bad html and I don't think you'll come across it too often. For the rest, this should work:

    $dom = new DOMDocument();

  @$dom->loadHTML($html);
        
  $metas = $dom -> getElementsByTagName('meta');

  foreach ($metas as $meta) {
      if ( $meta ->getAttribute('name') == 'description') {
      echo $meta->getAttribute('content');
      }       
    }
    PHP:
    Where $html is a string with your html data.

    How about the following:
    
// 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
    PHP:
