我先把我自己学习PHP的过程做一下概括：法式|数据|数据库   db.func:
<?
function GetRows( $Database, $Query ) {
   mysql_connect ("ftp", "root", "");
   $db = mysql_select_db( $Database );
   if ( ! $db ) {
      echo "没法保持数据库！";
      exit;
   }
   $rows = mysql_query( $Query );
   if ( ! $rows ) {
      echo "SQL指令毛病!";
      exit;
   }
   return $rows;
}
function ConnectDatabase( $Database ) {
   mysql_connect ("ftp", "root", "");
   $db = mysql_select_db( $Database );
   if ( ! $db ) {
      echo "没法保持数据库！";
      exit;
   }
}
?>
cratetable.php:
<?
function CreateTable() {
   $link = mysql_connect ("ftp", "root", "");
   $db = mysql_select_db("pcadmin");
   if ( ! $db ) {
      echo "毗连到数据库掉败！";
      exit;
   }
   $rows = mysql_query("select * from Profile");
   if ( ! $rows ) {
      $sql = "Create Table Profile (ID integer auto_increment primary key,Name char(255),Produce char(255),Lianluo char(255),Tel integer(15),Email char(255))";
      mysql_query($sql);
   }
   
   $rows = mysql_query("select * from Aplication");
   if ( ! $rows ) {
      $sql = "Create Table Aplication(Name char(255) primary key,IP char(255),Ap char(255),Directory char(255))";
      mysql_query($sql);
   }
   mysql_close ($link);
}
CreateTable();
?>
