  ]
], [
  "user_id[<]" => 1000
] );

查詢

復制代碼 代碼如下:
$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"
