New Learning static function why return data is empty

New Learning static function Why is the returned data empty?
Recently in learning the static function, build a code like this. Curl Gets the Web page source code, take out the title and so on, why does my code return nothing? Where's the problem? Can you explain it in detail? Thank you.

        $url = ' www.php.net/archive/2012.php ';
if (! $url) {
Exit
}
echo Testclass::gettitle ($url);
Class TestClass
{
static function GetTitle ($url)
{
$text = self::gethtml ($url);
Preg_match ("/(
 
  
   
  ) (. *) (<\/h1>)/is", $text, $h 1tags); 
  
   
$title =  $h 1tags[0];
  
   
if (! $title) return false;
  
   
return $title;
  
   
}
  
   
static function gethtml ($url) {
  
   
$ch = Curl_init ();
  
   
curl_setopt ($ch, Curlopt_url, $url);
  
   
$htmls = curl_exec ($ch);
  
   
Curl_close ($ch);
  
   
if (! $htmls) return false;
  
   
return $htmls;
  
   
}
  
   
}

That's your regular string of mistakes.
/( ) (. *) (<\/h1>)/is

Of course, to make your code run as you expect, you also need to
curl_setopt ($ch, Curlopt_returntransfer, true);
In $htmls = Curl_exec ($ch); Before

Isn't it possible to run your code to show the entire page?

Set, or output blank, nothing, my php Version 5.3.8.
I want to go back to the regular out

the text part.

How about a new method? No.

So you're probably not loading curl extensions?

Simple Curl code can return the contents of the www.php.net. But build a static function, but nothing.

 $url = ' www.php.net/archive/2012.php '; 
 $ch = Curl_init (); 
 curl_setopt ($ch, Curlopt_url, $url); 
 curl_setopt ($ch, Curlopt_returntransfer, true); 
 $htmls = curl_exec ($ch); 
 Curl_close ($ch); 
 Echo $htmls;

That's your regular rule. The string is incorrectly
/( ) (. *) (<\/h1>)/is

Does it make sense to remove the IS?
