PHP 常见mongodb查询操作

<?php// 欄位字串為$querys = array("name"=>"shian"); // 數值等於多少$querys = array("number"=>7); // 數值大於多少$querys = array("number"=>array('$gt' => 5)); // 數值大於等於多少$querys = array("number"=>array('$gte' => 2)); // 數值小於多少$querys = array("number"=>array('$lt' => 5)); // 數值小於等於多少$querys = array("number"=>array('$lte' => 2)); // 數值介於多少$querys = array("number"=>array('$gt' => 1,'$lt' => 9)); // 數值不等於某值$querys = array("number"=>array('$ne' => 9)); // 使用js下查詢條件$js = "function(){    return this.number == 2 && this.name == 'shian';}";$querys = array('$where'=>$js); // 欄位等於哪些值$querys = array("number"=>array('$in' => array(1,2,9))); // 欄位不等於哪些值$querys = array("number"=>array('$nin' => array(1,2,9))); // 使用正規查詢$querys = array("name" => new MongoRegex("/shi/$i")); // 或$querys = array('$or' => array(array('number'=>2),array('number'=>9)));?>
