php7里面使用如下库，操作比较复杂
PHP7连接MongoDB语法如下：
//参数规则: mongodb://账号:密码@IP:端口/数据库
$manager = new \\MongoDB\\Driver\\Manager("mongodb://php:123456@localhost:27017/php");
插入数据
//1.连接MongoDB
$manager = new \\MongoDB\\Driver\\Manager("mongodb://php:123456@localhost:27017/php");
//2.创建一个BulkWrite对象
$bulk = new \\MongoDB\\Driver\\BulkWrite();
$bulk->insert([\'name\' => \'bashlog\', \'age\' => 26, \'email\' => \'bashlog@foxmail.com\']);
$bulk->insert([\'name\' => \'itbsl\', \'age\' => 12, \'email\' => \'itbsl@foxmail.com\']);
//3.执行插入
$manager->executeBulkWrite(\'php.stu\', $bulk);
查看插入情况
查询数据
//1.连接MongoDB
$manager = new \\MongoDB\\Driver\\Manager("mongodb://php:123456@localhost:27017/php");
//2.创建一个Query对象
$filter = [\'age\' => [\'$gt\' => 5]];
$options = [
\'sort\' => [\'age\' => -1]
];
$query = new \\MongoDB\\Driver\\Query($filter, $options);
$cursor = $manager->executeQuery(\'php.stu\', $query);
foreach ($cursor as $document) {
var_dump($document);
}
更新数据
//1.规则:mongodb://账号:密码@IP:端口/数据库
$manager = new \\MongoDB\\Driver\\Manager("mongodb://php:123456@localhost:27017/php");
//2.创建一个BulkWrite对象
$bulk = new \\MongoDB\\Driver\\BulkWrite();
$bulk->update(
[\'age\' => 12],
[\'$set\' => [\'name\' => \'kitty\', \'age\' => 122]],
[\'multi\' => false, \'upsert\' => false]
);
$writeConcern = new MongoDB\\Driver\\WriteConcern(MongoDB\\Driver\\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite(\'php.stu\', $bulk, $writeConcern);
删除数据
//1.规则:mongodb://账号:密码@IP:端口/数据库
$manager = new \\MongoDB\\Driver\\Manager("mongodb://php:123456@localhost:27017/php");
//2.创建一个BulkWrite对象
$bulk = new \\MongoDB\\Driver\\BulkWrite();
//limit为1时，删除第一条匹配的数据
//limit为0时，删除所有匹配数据
$bulk->delete([\'age\' => 122], [\'limit\' => 1]);
$writeConcern = new MongoDB\\Driver\\WriteConcern(MongoDB\\Driver\\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite(\'php.stu\', $bulk, $writeConcern);
