如何將MySQL轉換為mysqli？基于下面的代碼，我如何將其轉換為mysqli？是否就像更改*mysql_query($sql)一樣簡單？；到mysqli_query($SQL); ?**<?PHP//in my header file that is included on every page I have this$DB["dbName"] = "emails";$DB["host"] = "localhost";$DB["user"] = "root";$DB["pass"] = "";$link = mysql_connect($DB['host'], $DB['user'], $DB['pass']) or die("<center>An Internal Error has Occured. Please report following error to the webmaster.<br><br>".mysql_error()."'</center>");mysql_select_db($DB['dbName']);// end header connection part// function from a functions file that I run a mysql query through in any page.function executeQuery($sql) {    $result = mysql_query($sql);    if (mysql_error()) {        $error = '<BR><center><font size="+1" face="arial" color="red">An Internal Error has Occured.<BR> The error has been recorded for review</font></center><br>';        if ($_SESSION['auto_id'] == 1) {            $sql_formatted = highlight_string(stripslashes($sql), true);            $error .= '<b>The MySQL Syntax Used</b><br>' . $sql_formatted . '<br><br><b>The MySQL Error Returned</b><br>' . mysql_error();        }        die($error);    }    return $result;}// example query ran on anypage of the site using executeQuery function$sql='SELECT auto_id FROM friend_reg_user WHERE auto_id=' .$info['auto_id'];$result_member=executequery($sql);if($line_member=mysql_fetch_array($result_member)){    extract($line_member);} else {    header("location: index.php");    exit;}?>
