Compile and install PHP7

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 only supports the new version of API (mongodb > 2.6.X version) after compilation

CURL operations

 $bulk->insert(['_id' => 2]);
 $bulk->insert(['_id' => 3,

 $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();

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);}
