]);修改
代码如下：
$database = new medoo ( "my_database" ); $database->update ( "account", [ "type" => "user", // All age plus one "age[+]" => 1, // All level subtract 5 "level[-]" => 5, "lang" => [ "en", "fr", "jp", "cn", "de" ] ], [ "user_id[<]" => 1000 ] );
查询
代码如下：
$database = new medoo ( "my_database" ); $datas = $database->select ( "account", [ "user_name", "email" ], [ "user_id[>]" => 100 ] ); // $datas = array( // [0] => array( // "user_name" => "foo", // "email" => "[email protected]" // ), // [1] => array( // "user_name" => "cat", // "email" => "[email protected]" // ) // ) foreach ( $datas as $data ) { echo "user_name:" . $data ["user_name"] . " - email:" . $data ["email"] . "<br>"; } // Select all columns $datas = $database->select ( "account", "*" ); // Select a column $datas = $database->select ( "account", "user_name" ); // $datas = array( // [0] => "foo", // [1] => "cat" // )
