Compile and install PHP7 Mongdb extension

#First install a dependent library yum -y install openldap-develwget https://pecl.php.net/get/mongodb-1.1.1.tgz /home/server/php7/bin/phpize #Compile based on your own Depends on the 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:

The previous version used the mongo.so extension and the old php-mongodb api
It is no longer supported in PHP7, at least not yet.
The latest mongodb that supports PHP7 is compiled and only supports the new version of the API (mongodb > 2.6.X version)

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(...)  
["max_bson_size"]=>  
int(16777216)

["sec_latency_ms"]=>  
int(15)  
["peers"]=>

}}

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);}
