PHP7 MongodbAPI usage details

This article mainly introduces detailed information about the use of MongodbAPI in PHP7. For more information, see compile and install PHP7.

Compile and install the PHP7 Mongdb extension

# First install a dependency Library yum-y install openldap-develwget https://pecl.php.net/get/mongodb-1.1.1.tgz/home/server/php7/bin/phpize # depending on your own PHP environment. /configure -- with-php-config =/home/server/php7/bin/php-config make & make install # if successful, generate a mongodb. so extension in lib/php/extensions/no-debug-non-zts-20151012/modify php. ini configuration extension = mongodb. so

Note:

Earlier versions used mongo. so extensions, and the old php-mongodb api
PHP7 is not supported, at least not currently.
Mongodb with the latest support for PHP7 only supports the new version of API after compilation (mongodb> 2.6.X)

Mongodb API operations

Initialize Mongodb connection

$manager = new MongoDB/Driver/Manager("mongodb://127.0.0.1:27017"); var_dump($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(...)

CURL operation

$bulk = new MongoDB/Driver/BulkWrite(['ordered' => true]);$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());

Query

$filter = array();$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);}
