Question

我尝试使用if语句测试mysql连接。看起来像这样

    <php
    $mysql_host = "mysql12.000webhost.com";
    $mysql_database = "a3860164_users";
    $mysql_user = "a3860164_admin";
    $mysql_password = "admin1";


    $conn = new mysqli($mysql_host, $mysql_user, $mysql_password, $mysql_database);
    if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
    } 

    $sql = "SELECT `email` FROM  `users` ";
    $result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
    if (strpos($row,$_POST[email]) !== false) {
    header( 'Location: /register.html?message=This email is already registered' ) ;
}
}
}

$sql = "INSERT INTO table_name (`data`,`email`,`password`) VALUES (NULL, $_POST[email], $_POST[password])";

if ($conn->query($sql) === TRUE) {
    header( 'Location: /register.html?message=An error occured. Try again.' ) ;
} else {
    header( 'Location: /register.html?message=An error occured. Try again.' ) ;
}
</php>

＆gt; key关闭php标签，以便我的其余PHP代码无法运行。我怎样才能解决这个问题？这是在第三方主机上。

<?php
$con=mysqli_connect("localhost","wrong_user","my_password","my_db");
// Check connection
if (!$con)
  {
  die("Connection error: " . mysqli_connect_error());
  }
?>

PHP结束与＆gt;键
