How to insert data into MongoDB with PHP

How PHP inserts data into MongoDB

MongoDB is a popular NoSQL database known for its powerful performance and flexible data model. In PHP, we can use the MongoDB extension to connect and operate the MongoDB database. This article explains how to insert data into MongoDB using PHP and provides code examples.

Before you begin, make sure you have the MongoDB extension installed and enabled. The MongoDB extension can be enabled by adding the following line in the php.ini file:

extension=mongodb.so

Next, we need to connect to the MongoDB database. You can connect using MongoDB's constructor as shown below:

<?php
$mongo = new MongoDBDriverManager("mongodb://localhost:27017");
?>

The above code will establish a connection on the default MongoDB port 27017 on localhost. You can change the host and port according to the actual situation.

Next, we define a document to be inserted. MongoDB uses documents to store data, and a document is a collection of key-value pairs. Documents can be represented using PHP’s arrays, as shown below:

<?php
$document = [
    'name' => 'John',
    'age' => 25,
    'email' => 'john@example.com'
];
?>

In the above example, we have defined a document that contains name, age, and email.

Now, we will use MongoDB’s BulkWrite object to insert documents into the collection. BulkWrite objects allow us to perform multiple operations in a single request.

<?php
$bulk = new MongoDBDriverBulkWrite;
$bulk->insert($document);
$mongo->executeBulkWrite('database.collection', $bulk);
?>

In the above code, we create a BulkWrite object and use the insert() method to add the document to be inserted to the BulkWrite object. We then use the executeBulkWrite() method to insert data into the specified database and collection.

Finally, we need to confirm whether it is successful after inserting. You can check whether the insertion operation was successful by catching the exception or using the getInsertedCount() method.

<?php
try {
    // 插入操作
    $mongo->executeBulkWrite('database.collection', $bulk);

    // 获取插入的记录数
    $insertCount = $bulk->getInsertedCount();
    echo "成功插入{$insertCount}条记录";
} catch (MongoDBDriverExceptionException $e) {
    echo "插入失败：" . $e->getMessage();
}
?>

In the above code, we perform the insertion operation in the try block. If successful, we will use the getInsertedCount() method to get the number of inserted records and print the number of successfully inserted records on the screen. If the insertion fails, we will catch the exception in the catch block and print the error message.

This is the basic steps on how to insert data into MongoDB using PHP. Following the above steps, we can connect to the MongoDB database, define the document to be inserted, and then use the BulkWrite object to insert the document into the collection and confirm the success of the insertion operation as needed.
