Question

i wrote simple 3 functions to scrape titles , description and keywords of simple html page
this is the first function to scrape titles

function getPageTitle ($url)
{
    $content = $url;
    if (eregi("<title>(.*)</title>", $content, $array)) {
        $title = $array[1];
        return $title;
    }
}

and it works fine
and those are 2 functions to scrape description and keywords and those not working

function getPageKeywords($url)
{
    $content = $url; 
    if ( preg_match('/<meta[\s]+[^>]*?name[\s]?=[\s\"\']+keywords[\s\"\']+content[\s]?=[\s\"\']+(.*?)[\"\']+.*?>/i', $content, $array)) { 
        $keywords = $array[1];  
        return $keywords; 
    }  
}
function getPageDesc($url)
{
    $content = $url; 
    if ( preg_match('/<meta[\s]+[^>]*?name[\s]?=[\s\"\']+description[\s\"\']+content[\s]?=[\s\"\']+(.*?)[\"\']+.*?>/i', $content, $array)) { 
        $desc = $array[1];  
        return $desc; 
    }  
}

i know there may be something wrong with the preg_match line but i really don’t know
i tried it so much things but it doesn’t work

Why not use get_meta_tags? PHP Documentation Here

<?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
?>

NOTE You can change the parameter to either a URL, local file or string.
