在VSCode中使用PHP连接数据库,通常会用到PDO(PHP Data Objects)或MySQLi扩展。以下是简单的步骤:
1. 安装PHP插件:首先确保你的VSCode已经安装了适合的PHP插件,如PHP Intelephense、PHP Debug等。
2. 配置环境变量:确保你的系统已安装并配置好PHP和数据库驱动,例如mysqli或PDO。
3. 连接数据库的代码示例(使用PDO):
```php
<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// 设置 PDO 错误模式为异常
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
} catch(PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
$conn = null;
?>
```
4. 对于MySQLi扩展,连接代码类似,只是构造函数略有不同:
```php
<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
```
5. 关闭连接:
记得在操作完成后关闭连接,如上面的$conn = null;
