Cant get title and meta description from URL?

Hi

I am trying to pull title and meta description from an URL..

To pull the URL I am using the code from http://www.dreamincode.net/code/snippet4625.htm...

Code: Select all

function getTitle($Url){
        $str = file_get_contents($Url);
        if(strlen($str)>0){
                preg_match("/\<title\>(.*)\<\/title\>/",$str,$title);
                return $title[1];
        }
}
//Example:
echo getTitle("http://www.cnn.com");
And to pull the meta description I am using the code from http://php.net/manual/en/function.get-meta-tags.php.

Code: Select all

// Assuming the above tags are at www.example.com
$tags = get_meta_tags('http://www.cnn.com/')
 or die("Could not fetch meta tags");

// 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
So my complete code looks like this:

Code: Select all

<html>
<head>
</head>
<body>
<?php
function getTitle($Url){
        $str = file_get_contents($Url);
        if(strlen($str)>0){
                preg_match("/\<title\>(.*)\<\/title\>/",$str,$title);
                return $title[1];
        }
}
//Example:
echo getTitle("http://www.cnn.com");


// Assuming the above tags are at www.example.com
$tags = get_meta_tags('http://www.cnn.com/')
 or die("Could not fetch meta tags");

// 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

?>
Test!
</body>
</html>
But it wont work... All I get is "Could not fetch meta tags".. I've tried different URLs and such but still wont work ..

Anyone have an idea?

You didn't say if the get title worked or not, but just a shot in the dark:

Code: Select all

echo ini_get('allow_url_fopen');
And you should be using this while developing:

Code: Select all

error_reporting(E_ALL);
ini_set('display_errors', '1');

If anyone wanna know, here is the code I used:

Code: Select all

<html>
<head>
</head>
<body>
<?php
$news = $_GET["news"];

function getTitle($Url){
        $str = file_get_contents($Url);
        if(strlen($str)>0){
                preg_match("/\<title\>(.*)\<\/title\>/",$str,$title);
                return $title[1];
        }
}
//Example:
echo getTitle("$news");

echo "<br><br>";


// Assuming the above tags are at www.example.com
$tags = get_meta_tags($news)
 or die("Could not fetch meta tags");


echo $tags['keywords'];  // a php manual
echo "<br><br>";
echo $tags['description'];  // a php manual


?>
</body>
</html>
