Question

我正在尝试将带有PDO的布尔值插入MySQLdatabase。如果$data['age2']是false，则不会进行插入，但是如果true，则可以进行插入。如果我使用->bindParam()方法，它将再次起作用。但是，如果有可能，我将在关联数组中传递变量。你知道我在做什么错吗？在代码的底部，我也插入了用于创建表的代码（我想插入到表中）。谢谢

<?php
$host = 'localhost';
$user = 'root';
$password = '12345';
$dbName = 'pdo';

// set DSN data sorce name
$dsn = "mysql:host={$host};dbname={$dbName}";

// create pdo instance
$pdoConn = new PDO($dsn, $user, $password);
$pdoConn->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_OBJ);

$data = [
    ':fname' => 'Bob',
    ':sname' => 'Desaunois',
    ':age' => '18',
    ':age2' => true
];
$sql = 'INSERT INTO posts (title, body, author, is_published) VALUES (:fname, :sname, :age, :age2)';
$statement = $pdoConn->prepare($sql);

$statement->execute($data);

/*
SHOW CREATE TABLE posts;
'posts', 'CREATE TABLE `posts` (\n  `id` int(11) NOT NULL AUTO_INCREMENT,\n  `title` char(255) NOT NULL,\n  `body` text NOT NULL,\n  `author` char(255) NOT NULL,\n  `is_published` tinyint(1) DEFAULT \'0\',\n  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,\n  PRIMARY KEY (`id`)\n) ENGINE=InnoDB AUTO_INCREMENT=150 DEFAULT CHARSET=latin1'
posts, CREATE TABLE `posts` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` char(255) NOT NULL,
  `body` text NOT NULL,
  `author` char(255) NOT NULL,
  `is_published` tinyint(1) DEFAULT '0',
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=150 DEFAULT CHARSET=latin1
