~~~
$last_user_id = $database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25
]);
~~~
#### 序列化数组
默认情况下，你要将数组插入会被序列化`serialize()`, 也可以使用 JSON `json_encode()`.
~~~
$last_user_id = $database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25,
"lang" => ["en", "fr", "jp", "cn"] // => 'a:4:{i:0;s:2:"en";i:1;s:2:"fr";i:2;s:2:"jp";i:3;s:2:"cn";}'
]);
$last_user_id = $database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25,
"(JSON) lang" => ["en", "fr", "jp", "cn"] // => '["en","fr","jp","cn"]'
]);
~~~
#### 多条数据插入
可以同时插入多条数据.
~~~
$last_user_id = $database->insert("account", [
[
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25,
"city" => "New York",
"(JSON) lang" => ["en", "fr", "jp", "cn"]
],
[
"user_name" => "bar",
"email" => "bar@foo.com",
"age" => 14,
"city" => "Hong Kong",
"(JSON) lang" => ["en", "jp", "cn"]
]
]);
~~~
#### 使用 SQL 函数
在一些特殊的情况下,您可能需要使用SQL函数来处理数据。在字段前加入#号即可
~~~
$last_user_id = $database->insert("account", [
"user_name" => "bar",
"#uid" => "UUID()"
]);
