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 https://pecl.php.net/get/mongodb-1.1.1.tgz /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);}
