"AND" => [
"type" => "business"
"age[<]" => 18
]
]);

修改

代码如下:

$database->update ( "account",[ "type" => "user",

// All age plus one
"age[+]" => 1,

// All level subtract 5
"level[-]" => 5,

"lang" => [
"en",
"cn",
"de"
]
],[
"user_id[<]" => 1000
] );

查询

代码如下:

$datas = $database->select ( "account",[ "user_name", "email" ],[ "user_id[>]" => 100 ] );

// $datas = array( // [0] => array( // "user_name" => "foo", // "email" => "[e-mail]" // ), // [1] => array( // "user_name" => "cat", // "email" => "[e-mail]" // ) // )

foreach ( $datas as $data ) { echo "user_name:" . $data ["user_name"] . " - email:" . $data ["email"] . "
"; }

// Select all columns $datas = $database->select ( "account","*" );

// Select a column $datas = $database->select ( "account","user_name" );

// $datas = array(
// [0] => "foo",
// [1] => "cat"
// )
