To this end, many packages will include things like Unit Tests and documentation. This way I can run the unit Tests on my own to validate the package first. This is all fine and good, except when I don’t want them. There are times when I know the package well enough, or have used it enough, to not have to bother with any of that.5: Optimize your autoloadRegardless of whether you --prefer-dist or --prefer-source, when your package is incorporated into your project with require, it just adds it to the end of your autoloader. This isn’t always the best solution. Therefore Composer gives us the option to optimize the autoloader with the --optimize switch. Optimizing your autoloader converts your entire autoloader into classmaps. Instead of the autoloader having to use file_exists() to locate a file, Composer creates an array of file locations for each class. This can speed up your application by as much as 30%.$ composer dump-autoload --optimize$ composer require monolog/monolog:~1.18.0 -o
composer require --dev phpunit/phpunit ^6.0composer global require phpunit/phpunit ^6.0~/.composer/vendor/bin. If you add this directory to your path, then from any project, you can execute PHPUnit. However, as noted above, if you ever upgrade your globally installed packages then you will have problems.composer global updatecomposer require --dev.wget https://phar.phpunit.de/phpunit-6.0.pharchmod +x phpunit-6.0.pharsudo mv phpunit-6.0.phar /usr/local/bin/phpunitphpunit --version

composer require mongodb/mongodb
vendor directory containing the required files.connect.php. Add the following code:
<?php
require 'vendor/autoload.php';
use MongoDB\Client;
$client = new Client("mongodb://localhost:27017");
?>
Client class. We then create a new instance of the Client class, specifying the MongoDB server's connection URL. Adjust the URL if your MongoDB server is running on a different host or port.insertOne() method. Here's an example:<?php
$collection = $client->test->users;
$newUser = [
'name' => 'John',
'email' => '[email protected]',
'age' => 25
];
$insertResult = $collection->insertOne($newUser);
echo "Inserted document ID: " . $insertResult->getInsertedId();
?>
users collection within the test database. We create a new document as an associative array and then use the insertOne() method to insert it into the collection. Finally, we retrieve and display the ID of the inserted document using the getInsertedId() method.find() method. Here's an example:<?php
$collection = $client->test->users;
$documents = $collection->find();
foreach ($documents as $document) {
echo $document['name'] . ': ' . $document['email'] . "\n";
}
?>
users collection. We iterate over the result using a foreach loop and access specific fields, such as the name and email, to display their values.updateOne() method. Here's an example:<?php
$collection = $client->test->users;
$updateResult = $collection->updateOne(
['name' => 'John'],
['$set' => ['age' => 30]]
);
echo "Modified " . $updateResult->getModifiedCount() . " document(s).";
?>
age field of the document with the name 'John' using the $set operator. The updateOne() method updates the first matching document. We then retrieve the number of modified documents using the getModifiedCount() method.deleteOne() method. Here's an example:<?php
$collection = $client->test->users;
$deleteResult = $collection->deleteOne(['name' => 'John']);
echo "Deleted " . $deleteResult->getDeletedCount() . " document(s).";
?>
deleteOne() method removes the first matching document, and we retrieve the number of deleted documents using the getDeletedCount() method.
