Question

当我尝试测试我的再生形式时，这个按摩出现了： “mysql扩展已弃用，将来将被删除：使用mysqli或PDO”

每次遇到新问题时我都会尝试更改我的代码，我对这些内容并不擅长任何人都可以帮助我，告诉我我的代码需要更改的内容吗？！

连接代码

    <?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_localhost = "localhost";
$database_localhost = "rsms database";
$username_localhost = "root";
$password_localhost = "";
$localhost = mysql_pconnect($hostname_localhost, $username_localhost, $password_localhost) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

这是我的源代码

    <?php require_once('Connections/localhost.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form")) {
  $insertSQL = sprintf("INSERT INTO users (email, DateOfBirth) VALUES (%s, %s)",
                       GetSQLValueString($_POST['email'], "text"),
                       GetSQLValueString($_POST['DateOfBirth'], "date"));

  mysql_select_db($database_localhost, $localhost);
  $Result1 = mysql_query($insertSQL, $localhost) or die(mysql_error());

  $insertGoTo = "PageAfterLogin.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $insertGoTo));
}

mysql_select_db($database_localhost, $localhost);
$query_RegesterUsers = "SELECT * FROM users";
$RegesterUsers = mysql_query($query_RegesterUsers, $localhost) or die(mysql_error());
$row_RegesterUsers = mysql_fetch_assoc($RegesterUsers);
$totalRows_RegesterUsers = mysql_num_rows($RegesterUsers);

目前在PHP中有三种连接MySQL数据库的方法。使用mysql_ *函数（已使用），mysqli_ *（首选）和PDO。

不再支持mysql_函数（并在PHP 7中删除），您不应再使用它们用于PHP脚本，并且应该使用MySQLi作为新的和改进的标准。

PDO是所有数据库安装的通用标准，例如MySQL，SQLite，MS SQL和PostgreSQL。

您所拥有的信息只是一个通知，您不需要使用PDO或MySQLI，但PHP会在您每次更改脚本时告诉您。

用Mysqli或PDO替换MySQL函数
