PHP delete语句的用法是什么

PHP中的delete语句用于从数据库中删除记录。其基本语法如下：

$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("Connection failed: " . $conn->connect_error);
}

// 删除记录
$sql = "DELETE FROM tablename WHERE condition";

if ($conn->query($sql) === TRUE) {
    echo "Record deleted successfully";
} else {
    echo "Error deleting record: " . $conn->error;
}

// 关闭连接
$conn->close();

在上面的代码中，DELETE FROM tablename WHERE condition 是删除记录的SQL语句。你需要将tablename替换为要删除记录的表名，将condition替换为符合要删除记录条件的条件语句。如果删除记录成功，将会输出Record deleted successfully，否则会输出错误信息。最后，记得关闭数据库连接。
