Your example will fail if I enter *1*2*3*

you should be searching for the contents of

**(contents)**

and nothing else. That will get you the name and the number.

Here is my example

$string = "**123naasdme456**";
preg_match("/[^\*+](?P<val>\w+)[^\*+]/",$string,$matches);
echo $matches[0];

will echo 123naasdme456

and here it is implemented into your code

function getReal($urlVar)
{
  if(preg_match("/[^\*+](?P<val>\w+)[^\*+]/",$urlVar,$matches))
  {
    return $matches[0];
  }
  return false; // or default value
}
$pid = getReal($_GET['pid']);
$name = getReal($_GET['pname']);

You should add an extra field in your database (table main_page) with the name name or something similar. Then you could:

if (!$_GET['pname']) {
  $pid = 'home';
} else {
  $pid = mysql_real_escape_string($pid);
  $sql = mysql_query("SELECT name FROM main_page WHERE name = '$pid'");

  if (mysql_num_rows($sql) == 1))
  {
     echo "Content";
  } else {
     echo "404 error. Couldn't find the page you were looking for.";
  }
}
