A must-have efficient text database for PHP: providing stability and performance for your applications

PHP is a widely used open source programming language that can be used to quickly build web applications. As the size of application data grows, many PHP developers find that using traditional relational databases causes performance issues and data storage limitations. In order to solve this problem, more and more people are beginning to use text databases.

Text database is a database that stores data in the form of text files and can be more efficient than relational databases when processing certain data types. And compared to traditional relational databases, text databases are cheaper to store because they don't require expensive servers or additional components.

In this article, we will introduce the most popular PHP text databases and provide code examples to help you provide better stability and performance for your applications.

1. Flat File Database

Flat File Database (FFDB) is a lightweight text database whose data is stored in plain text files. FFDB is a database designed for small databases. It is very easy to integrate and maintain, making it ideal for small to medium-sized projects. Here is sample code using FFDB:

//通过打开文件来初始化数据库
$db = dba_open('users.ffdb', 'n', 'flatfile');

//添加一个新用户
$key = dba_insert('John Doe', 'jdoe@gmail.com', $db);

//获取一个用户
$user = dba_fetch($key, $db);

//更新用户
$dba_replace($key, 'Jane Doe', 'jane@gmail.com', $db);

//删除用户
$dba_delete($key, $db);

Note that FFDB is a very basic database and is not suitable for large or high-load applications.

2. SQLite

SQLite is a widely used relational database that uses different storage methods such as plain text and binary files. In most cases, SQLite is very suitable for PHP applications.

Before using SQLite, you need to enable the SQLite extension on your PHP server. Here is sample code using SQLite:

//连接到数据库
$db = new SQLite3('database.db');

//添加一个用户
$db->exec("INSERT INTO users (name, email) VALUES ('John Doe', 'jdoe@gmail.com')");

//获取用户列表
$results = $db->query("SELECT * FROM users");
while ($row = $results->fetchArray()) {
   echo $row['name'] . " - " . $row['email'] . "<br />";
}

//更新用户
$db->exec("UPDATE users SET name='Jane Doe', email='jane@gmail.com' WHERE id=1");

//删除用户
$db->exec("DELETE FROM users WHERE id=1");

SQLite is a good choice for small databases. Its performance and stability are also adequate in most situations.

3. MongoDB

MongoDB is a very powerful text database when it comes to processing large amounts of unstructured data. When using MongoDB, data is stored in the form of documents (similar to JSON objects). MongoDB can scale to very large scales because of its vertical and horizontal scaling ease.

Before using MongoDB, you need to install the MongoDB extension on your PHP server. The following is sample code using MongoDB:

//连接到MongoDB数据库
$client = new MongoDBClient("mongodb://localhost:27017");

//获取MongoDB中的集合
$collection = $client->users->Information;

//添加一个用户
$insertOne = $collection->insertOne([
    'name' => 'John Doe',
    'email' => 'jdoe@gmail.com'
]);

//获取用户列表
$cursor = $collection->find();
foreach ($cursor as $document) {
    echo $document['name'] . " - " . $document['email'] . "<br />";
}

//更新用户
$updateResult = $collection->updateOne(
    ['name' => 'John Doe'],
    ['$set' => ['name' => 'Jane Doe', 'email' => 'jane@gmail.com']]
);

//删除用户
$deleteResult = $collection->deleteOne(['_id' => $insertOne->getInsertedId()]);

MongoDB is a large database that is very suitable for processing unstructured data.

Summary

When building PHP applications, it is very important to choose the right text database. The above three text databases have different advantages and scope of application. If you need to process large amounts of unstructured data, MongoDB will be the best choice. For small projects, FFDB or SQLite may be the best choices. For more efficient performance and better stability, it is recommended that you adopt best practices when using these databases.
