在查詢中使用數據之前，必須轉義“'”符號。
發生的情況是您的用戶在輸入字段中輸入“'”，而MySQL出現錯誤。
使用准備好的語句以自動方式處理該問題。
這是示例。
編輯：
像這樣編輯代碼：
if(! get_magic_quotes_gpc() )
{
$first_name = addslashes ($_POST['first_name']);
$last_name = addslashes ($_POST['last_name']);
$email_address = addslashes ($_POST['email_address']);
$phone_no = addslashes ($_POST['Phone_no']);
$user_name = addslashes ($_POST['user_name']);
$password = addslashes ($_POST['password']);
$sec_question = addslashes ($_POST['sec_question']);
$Answer = addslashes ($_POST['Answer']);
$Country = addslashes ($_POST['Country']);
$State = addslashes ($_POST['State']);
$city = addslashes ($_POST['city']);
$date_birth = addslashes ($_POST['date_birth']);
$gender = addslashes ($_POST['gender']);
}
else
{
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$email_address = $_POST['email_address'];
$phone_no = $_POST['Phone_no'];
$user_name = $_POST['user_name'];
$password = $_POST['password'];
$sec_question = $_POST['sec_question'];
$Answer = $_POST['Answer'];
$Country = $_POST['Country'];
$State = $_POST['State'];
$city = $_POST['city'];
$date_birth = $_POST['date_birth'];
$gender = $_POST['gender'];
}
它應該防止錯誤。
