MySQL connection freeze the runtime

I've tried almost every possible MySQL Server running on my computer or on the web server, And every connection causes the PHP Runtime to freeze. Any workout/solutions for that?

$mydbsql = mysql_pconnect("localhost:3301", "local", "local") or die("It doesn't even die");
 or...
 $mydbsql = mysql_pconnect("localhost:3306", "local", "local") or die("It doesn't even die");
  or...
  $mydbsql = mysql_pconnect("localhost:4430", "local", "local") or die("It doesn't even die");

Debugging the code shows that every line before running the connect function works fine but when It gets to the connection, It freeze the runtime (stucks at loading).

Edit: Just waited a long time and after that an error popped up.

HTTP Error 500.0 - Internal Server Error
The page cannot be displayed because an internal server error has occurred.

Does your mysql use port 3301 or port 3306? It might be that the port is wrong in your example?
