php操作mongodb

1.1、connect mongodb

$conn = new Mongo('192.168.63.179'); #连接远程主机，默认端口27017
$db = $conn->test; #选择一个数据库
$collection = $db->abc; #选择一个集合

1.2、 select

$where = 
    1.$db->users->find(array(), array("a" => 1, "b" => 1));
    2.[
            'name'=>['$exists'=>1] ,
            'age'=>[
                    '$ne'=>0,
                    '$lt'=>50,
                    '$exists'=>1] 
        ]   # 存在name字段，存在age字段，且age不等以0，小于50
$field = 
    1.['name'=>1,'age'=>1];
$rs = $collection->find($where)->fields($field);
foreach ($rs as $key => $value) {
    var_dump($value);
}

1.3、 insert

$arr = ['name'=>'wang',age=>19];
$collection->insert($arr);

1.4、 update

$where = ['name'=>'wang'];
$upd = [
            '$set'=>['name'=>'wangnan']
    ]
$collection->update($where,$upd);

1.5、delete

$where = ['age'=>19];
$collection->remove($where);
