问题描述
这是我第一次尝试做一个简单的PHP& MySql登录但收到此错误 - >不推荐使用：mysql_connect（）：不推荐使用mysql扩展，将来会删除它：在第11行的C：\ wamp \ www \ _login_form \ dbConfig.php中使用mysqli或PDO
和mysql和mysqli有什么区别？
这里分别是我的login.php代码和dbConfig.php代码：
login.php
This is first time I am trying to do a simple PHP & MySql login but am getting this error --> Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in C:\wamp\www\login_form\dbConfig.php on line 11
and what is the difference between mysql and mysqli ?
here is my login.php code and dbConfig.php code respectively:
login.php
<?php include "dbConfig.php";
$msg = "";
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$name = $_POST["name"];
$password = md5($_POST["password"]);
if ($name == '' || $password == '') {
$msg = "You must enter all fields";
} else {
$sql = "SELECT * FROM members WHERE name = '$name' AND password = '$password'";
$query = mysql_query($sql);
if ($query === false) {
echo "Could not successfully run query ($sql) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($query) > 0) {
header('Location: www.google.com');
exit;
}
$msg = "Username and password do not match";
}
}
?>
