mysql 添加单引号

// 使用PDO预处理语句
$stmt = $pdo->prepare("SELECT * FROM users WHERE name = :name");
$stmt->execute(['name' => $name]);

INSERT INTO users (name) VALUES ('O\'Reilly');

INSERT INTO users (name) VALUES ('O''Reilly');

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 预处理和绑定
$stmt = $conn->prepare("INSERT INTO users (name, email) VALUES (?, ?)");
$stmt->bind_param("ss", $name, $email);

// 设置参数并执行
$name = "John Doe";
$email = "john@example.com";
$stmt->execute();

echo "新记录插入成功";

$stmt->close();
$conn->close();
