PHP7之Mongodb API使用详解

编译安装php7

编译安装php7 mongdb扩展

#先安装一个依赖库yum -y install openldap-develwget /home/server/php7/bin/phpize   #根据自己编译的php环境而定./configure --with-php-config=/home/server/php7/bin/php-config make && make install#如果成功，生成一个mongodb.so扩展在lib/php/extensions/no-debug-non-zts-20151012/修改php.ini配置extension=mongodb.so

注：

以前版本用的是mongo.so扩展，老的php-mongodb api
在php7已经不支持了，至少目前不支持。
最新支持php7的mongodb 编译后 仅支持新版api(mongodb > 2.6.x版本)

mongodb api 操作

初始化mongodb连接

$manager = new mongodb/driver/manager("mongodb://127.0.0.1:27017"); var_dump($manager);
object(mongodb/driver/manager)#1 (3) 
{ 
["request_id"]=> int(1714636915) 
["uri"]=> string(25) "mongodb://localhost:27017" 
["cluster"]=> array(13) {  
["mode"]=>  string(6) "direct"  
["state"]=>  string(4) "born" 
["request_id"]=>  
int(0)  
["sockettimeoutms"]=>  
int(300000)  
["last_reconnect"]=>  
int(0)  
["uri"]=>  
string(25) "mongodb://localhost:27017"  
["requires_auth"]=>  
int(0)  
["nodes"]=>  
array(...)  
["max_bson_size"]=>  
int(16777216)  
["max_msg_size"]=>  
int(50331648)  
["sec_latency_ms"]=>  
int(15)  
["peers"]=>  
array(0) {  
} 
["replset"]=>  
null 
}}

curl操作

$bulk = new mongodb/driver/bulkwrite(['ordered' => true]);$bulk->delete([]);
$bulk->insert(['_id' => 1]);
$bulk->insert(['_id' => 2]);
$bulk->insert(['_id' => 3, 
'hello' => 'world']);$bulk->update(['_id' => 3], 
['$set' => ['hello' => 'earth']]);
$bulk->insert(['_id' => 4, 'hello' => 'pluto']);
$bulk->update(['_id' => 4], ['$set' => ['hello' => 'moon']]);
$bulk->insert(['_id' => 3]);
$bulk->insert(['_id' => 4]);
$bulk->insert(['_id' => 5]);
$manager = new mongodb/driver/manager('mongodb://localhost:27017');
$writeconcern = new mongodb/driver/writeconcern(mongodb/driver/writeconcern::majority, 1000);
try {  
$result = $manager->executebulkwrite('db.collection', $bulk, $writeconcern);
} 
catch (mongodb/driver/exception/bulkwriteexception $e) 
{  
$result = $e->getwriteresult();  
// check if the write concern could not be fulfilled  
if ($writeconcernerror = $result->getwriteconcernerror())
{printf("%s (%d): %s/n",  
$writeconcernerror->getmessage(),  
$writeconcernerror->getcode(),  
var_export($writeconcernerror->getinfo(), true)); 
}  
// check if any write operations did not complete at all  
foreach ($result->getwriteerrors() as $writeerror) {printf("operation#%d: %s (%d)/n",  
$writeerror->getindex(),  
$writeerror->getmessage(),  
$writeerror->getcode());  
}} catch (mongodb/driver/exception/exception $e)
{ 
printf("other error: %s/n", $e->getmessage());  
exit;}printf("inserted %d document(s)/n", $result->getinsertedcount());
printf("updated %d document(s)/n", $result->getmodifiedcount());

查询

$filter = array();$options = array(  
/* only return the following fields in the matching documents */  
"projection" => array("title" => 1,"article" => 1,  ),  
"sort" => array("views" => -1,  ),  "modifiers" => array('$comment'  => "this is a query comment",'$maxtimems' => 100,  
),);$query = new mongodb/driver/query($filter, $options);$manager = new mongodb/driver/manager("mongodb://localhost:27017");
$readpreference = new mongodb/driver/readpreference(mongodb/driver/readpreference::rp_primary);$cursor = $manager->executequery("databasename.collectionname", $query, $readpreference);
foreach($cursor as $document) 
{ 
var_dump($document);}
