insert
插入数据到表中
insert($table, $data)
table [string]
表名.
data [array]
插入到表里的数据.
Return: [number] 返回插入的id
$last_user_id = $database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25
]);
插入ID
如果你想要获取最后插入行的ID,你需要单独调用 id()方法
$database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25
]);
$account_id = $database->id();
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().
$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";}'
]);
$database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25,
"lang [JSON]" => ["en", "fr", "jp", "cn"] // => '["en","fr","jp","cn"]'
]);
类型自动检测
Medoo将在插入之前自动检测数据类型，并将其优化以存储到数据库中。
class Foo {
var $bar = "cat";
public function __wakeup()
{
$this->bar = "dog";
}
}
$object_data = new Foo();
$fp = fopen($_FILES[ "file" ][ "tmp_name" ], "rb");
$database->insert("account", [
// String value
"user_name" => "foo",
// Integer value
"age" => 25,
// Boolean value
"is_locked" => true,
// Array value
"lang" => ["en", "fr", "jp", "cn"],
// Array value encoded as JSON
"lang [JSON]" => ["en", "fr", "jp", "cn"],
// Object value
"object_data" => $object_data,
// Large Objects (LOBs)
"image" => $fp
]);
多条数据插入
可以同时插入多条数据.
$database->insert("account", [
[
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25,
"city" => "New York",
"lang [JSON]" => ["en", "fr", "jp", "cn"]
],
[
"user_name" => "bar",
"email" => "bar@foo.com",
"age" => 14,
"city" => "Hong Kong",
"lang [JSON]" => ["en", "jp", "cn"]
]
]);
PDOStatement
insert()返回的是PDOStatement对象,你可以通过它获取更多信息
$data = $database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25
]);
// Returns the number of rows affected by the last SQL statement
echo $data->rowCount();

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()"
]);
