连接mongodb：
$mongoObj = new Mongo("127.0.0.1" , array( ‘connect‘=>true, ‘persist‘=>true ));
选择库：
$mongoDB = $mongoObj->selectDB("wxdata");
选择集合:
$mongoColletion=$mongoDB->selectCollection("apachelog");
删除一个集合:
$mongoColletion->drop();
插入文档数据：
$mongoColletion->insert(array("firstname" => "Bob", "lastname" => "Jones" ));
修改更新文档数据：
$newdata = array(‘$set‘ => array("address" => "1 Smith Lane")); $mongoColletion->update(array("firstname" => "Bob"), $newdata); $mongoColletion->update( array("uri" => "/summer_pics"), array(‘$inc‘ => array("page hits" => 1)), array("upsert" => true) ); $mongoColletion->update( array("name" => "joe"), array("username" => "joe312", "createdAt" => new MongoDate()), array("upsert" => true) ); $today = array(‘$gt‘ => new MongoDate(), ‘$lt‘ => new MongoDate(strtotime("+1 day"))); $mongoColletion->update( array("birthday" => $today), array(‘$set‘ => array(‘gift‘ => $surprise)), array("multiple" => true) );
新增文档数据：
$obj = array(‘x‘ => 1); $mongoColletion->save($obj); $obj[‘foo‘] = ‘bar‘; // $obj 不能被再次插入，导致 duplicate _id 错误 //$mongoColletion->insert($obj); $mongoColletion->save($obj);
移除一个文档数据：
$mongoColletion->remove(array(‘httpstatus‘ => 200), array("justOne" => true));
统计文档数量：
$mongoColletion->count(array(‘httpstatus‘=>304));
查询一个文档：
$mongoColletion->findOne(array("httpstatus" => 200));
查看文档索引信息：
$mongoColletion->getIndexInfo();
构建文档索引：
// create an index on ‘httpstatus‘ ascending $mongoColletion->ensureIndex(array(‘httpstatus‘ => 1)); // create a unique index on ‘size‘ $mongoColletion->ensureIndex(array(‘size‘ => 1), array(‘unique‘ => true)); // create a compound index on ‘size‘ ascending and ‘status‘ descending $mongoColletion->ensureIndex(array(‘size‘ => 1, ‘status‘ => -1)); //全文索引 $mongoColletion->ensureIndex( array( ‘title‘ => ‘text‘, ‘desc‘ => ‘text‘, ), array( ‘name‘ => ‘ExampleTextIndex‘, ‘weights‘ => array( ‘title‘ => 100, ‘desc‘ => 30, ) ) );
关闭到mongodb的连接：
$mongoObj->close();
从php操作mongodb常用的函数就这么多了。
