PHP MongoDB 上下文选项

Introduction

PHPYou can interact with the MongoDB database through database extensions. For older versions of PHP, the mongo driver can be installed from PECL. Now superseded by the mongodb driver. Both drivers can be installed using precompiled binaries for Linux/Windows/MacOS operating systems. Alternatively, you can install manually from the source tarball available on github. In either case, the mongo or mongodb extension should be enabled in the php.ini settings.

The PHP MongoDB extension provides streaming context support using the mongodb context. The relevant context options are as follows

Options

log_cmd_insert ( array $server , array $document , array $writeOptions , array $protocolOptions )

This is a Callable function, used by log_cmd_insert context options when inserting a document

log_cmd_delete ( array $server , array $writeOptions , array $deleteOptions , array $protocolOptions )

This is a callback function used by the log_cmd_delete context options when a document is deleted

log_cmd_update ( array $server , array $writeOptions , array $updateOptions , array $protocolOptions )

This function is used by the log_cmd_update context options when updating a document

log_write_batch ( array $server , array $writeOptions , array $ batch , array $protocolOptions )

This function consists of log_write_batch context options when performing batch operations.

log_reply ( array $server , array $messageHeaders , array $operationHeaders )

This callback function is used when reading MongoDB replies

log_getmore (array $server, array $info)

When performing a GET_MORE operation, this callable function is controlled by log_getmore Context options

log_killcursor (array $server, array $info)

Callback when executing KILLCURSOR operation

$server The array contains basic information of the following parameters

hash− Server hash, for example: localhost:27017;-;X;56052

type - Node type (primary/secondary/mongos/arbiter) - 2

max_bson_size - Maximum BSON size for lines accepted by this node - 16777216

max_message_size - Lines accepted by this node Maximum message size on - 48000000

request_id − Request identifier for this message − 42

How can you prevent session fixation attacks?Apr 28, 2025 am 12:25 AM

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

How do you implement sessionless authentication?Apr 28, 2025 am 12:24 AM

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

What are some common security risks associated with PHP sessions?Apr 28, 2025 am 12:24 AM

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

How do you destroy a PHP session?Apr 28, 2025 am 12:16 AM

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How can you change the default session save path in PHP?Apr 28, 2025 am 12:12 AM

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(

Give an example of storing an array in a PHP session.Apr 27, 2025 am 12:20 AM

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
