未捕获的错误：调用未定义的函数 mysql_escape_string（）

致命错误：未捕获错误：调用未定义的函数 mysql_escape_string（） 在 C：\xampp\htdocs\phoenixproject\register.php：16 堆栈跟踪： #0 {main} 在 C：\xampp\htdocs\phoenixproject\register 中抛出.php在第 16 行

如何解决这个问题？

<?php
require("config.php");
?>
<?php
if(isset($_POST['submit'])){

$email1 = $_POST['email1'];
$email2 = $_POST['email2'];
$pass1 = $_POST['pass1'];
$pass2 = $_POST['pass2'];

if($email1 == $email2) {
    if($pass1 == $pass2) {
//All good. Nastavi broo.

$name = mysql_escape_string($_POST['name']);
$lname = mysql_escape_string($_POST['lname']);
$uname = mysql_escape_string($_POST['uname']);
$email1 = mysql_escape_string($email1);
$email2 = mysql_escape_string($email2);
$pass1 = mysql_escape_string($pass1);
$pass2 = mysql_escape_string($pass2);

mysql_query("INSERT INTO `users` (`id`, `name`, `lname`, `uname`, `email`, `pass`) VALUES (NULL, '$name', '$lname', '$uname', '$email1', '$pass1')") or die (mysql_error());



}else{
  echo "Sorry, your password is not corrext.";
  exit();
}
}else{
  echo "Sorry!";
}

} // brace for submit conditional

$form = <<<EOT
<form action="register.php" method="POST">
First Name: <input type="text" name="name" /></br>
Last Name: <input type="text" name="lname" /></br>
Username: <input type="text" name="uname" /></br>
Email: <input type="text" name="email1" /></br>
Confirm Email: <input type="text" name="email2" /></br>
Password: <input type="password" name="pass1" /></br>
Confirm Password: <input type="password" name="pass2" /></br>
<input type="submit" value="Register" name="submit" />
</form>
EOT;
echo $form;

?>

好吧，我知道我试图混合mysql和mysqli....
