You String is :- 

$str ='<a href="http://facebook.com/feelingblue">Facebook</a>';

You may extract the href value by doing this :-

preg_match_all('~<a(.*?)href="([^"]+)"(.*?)>~', $str, $matches);

Removing http://

$url = str_replace ('http://', '', $matches[2]);

Remove rest of the things after .com

$url = preg_replace ('/(\.com).*/','$1',$url);

Desired output would be

facebook.com

Try this,

$string ='<a href="http://facebook.com/feelingblue">Facebook</a>';
if (strpos($string, 'facebook') !== false) {
    $facebookUrl = "http://www.facebook.com";
    $regEx = "/(?<=href=(\"|'))[^\"']+(?=(\"|'))/";
    $newUrl = preg_replace($regEx,$facebookUrl,$string);
}
echo $newUrl;

I hope this helps.

I am assuming that you fetching these values from DB

$url = 'http://facebook.com/feelingblue'; // this is the url you are getting

if (strpos($url , 'facebook') !== false) {
    $url = "https://facebook.com";
}

$string ='<a href="'.$url.'">Facebook</a>'

for more information

Use RegExp, if you are searching from the whole document.

preg_replace_callback('(<a href=")([^"]+)(">([^<]+)</a>)', function($match){
    return $match[1] . "//example.com" . $match[3];
}, $html);

If you just want Facebook, you can add a check if($match[4] === "Facebook") and/or if($match[2] === "http://facebook.com/feelingblue")

Use this code,

$string ='<a href="http://facebook.com/feelingblue">Facebook</a>';
echo preg_replace('#http://facebook.com/([^"]+)#is', 'http://www.facebook.com', $string );

Thanks Amit
