使用beantalk和PHP连接到AWS RDS数据库

Question

In PHP 7, As I try to connect to the Beanstalk I have set up, I receive the error:

Fatal error: Uncaught Error: Class 'mysql' not found in C:\\Apache24\\htdocs\\php_file.php, Stack trace: #0 {main} thrown in C:\\Apache24\\htdocs\\php_file.php on line 41.

This server uses AWS RDS running MYSQL, and I am using apache 2.4 to localhost (for testing).

The code I'm using is:

$servername = "MY BEANSTALK CONNECTION";
$username = "Username";
$password = "PSSWD";
$dbname = "DBNAME";

$conn = new mysql($servername, $username, $password, $dbname);

$sql = "SELECT * FROM column";
$result = $conn->query($sql);

$conn->close();

My updated code uses mysqli, but is still getting the same error.

Answer 1

From PHP documentation mysql class is deprecated since version 5.5 and removed in version 7. that's why you're receiving the class not found error.

Try using mysqli . The PHP documentation has good examples on this. Look at example 2. I've pasted part of the example in this post for you. https://www.php.net/manual/en/function.mysql-connect.php

<?php
$mysqli = new mysqli("example.com", "user", "password", "database");
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: " . $mysqli->connect_error;
}

$res = $mysqli->query("SELECT 'choices to please everybody.' AS _msg FROM DUAL");
$row = $res->fetch_assoc();
echo $row['_msg'];
?>

Answer 2

改用mysql_connect（$ servername，$ username，$ password）。
