";    echo $value['_id'];    echo '
name:';    echo $value['name'];    echo "
sex:";    echo $value['sex'];    echo "

";}複製代碼image 條件尋找$arr=array("name"=>"22");$cursor = $collection->find($arr);修改資料image 複製代碼$newdata = array('$set' => array("email" => "test@test.com"));$collection->update(array("name" => "22"), $newdata);var_dump($collection); $arr=array("name"=>"22");$cursor = $collection->find($arr);foreach($cursor as $key => $value){ echo "
