Question

Is it possible to get page description from page url without slowdowing the page load? via java script or php or any language?

For example I would send this input:

http://www.facebook.com

and get this output:

Facebook is a social utility that connects people with friends and others who work, study and live around them. People use Facebook to keep up with friends, ...

How I can do it?

Answer 1

You need the function file_get_contents($url) . For more help, refer to this

1: http://php.net/manual/en/function.file-get-contents.php . You may need to do urlencode if the URL contains some spaces . As for the parsing part, I have found some code on the web . Here is the link. Do let know

Code :

 <?php
function getMetaTitle($content){
//echo "AAAAA".$content;
$pattern = "|<[\s]*title[\s]*>([^<]+)<[\s]*/[\s]*title[\s]*>|Ui";
if(preg_match($pattern, $content, $match))
{
    //echo $match[1];
    return $match[1];
}
else
    return false;
}   
    //echo "<h1>Hello World!</h1>";
$url = "your url here";

$str = file_get_contents($url);

$title1 = getMetaTitle($str);
echo $title1;
//echo htmlentities($str);
?>
