In today's Internet era, the rapid development and popularization of technology have made it easier and more common to build Web applications. However, during web application development, the connection between database and programming language is very critical. MySql database is a very popular choice for PHP developers.
However, just connecting MySql and PHP to each other is not enough. To establish a closer connection, optimization needs to be done in many aspects.
1. Use PDO to connect
Using PDO to connect is the first step to establish a closer MySql and PHP connection. PDO provides an abstraction layer and support for multiple database backends, effectively connecting PHP to MySql.
The advantage of using PDO is that it provides some basic functions and common APIs required by developers. Compared with other database connection methods, PDO has higher performance, richer functions and security. In addition, PDO can also support multiple database engines, allowing developers to easily change the type of database without changing the application code.
2. Use MySql extension
If you choose to use MySql extension as the connection method, you must be careful not to confuse it with MySQLi. MySQLi is another MySql extension for PHP that provides similar functionality to PDO.
One of the benefits of using the MySql extension is that its performance is very high. This means that developers can quickly read and manipulate data from the MySql database in PHP code. In addition, MySql extensions can also cooperate very well with other extensions, class libraries and frameworks, making the development process more efficient.
3. Using the MySql function in PHP
When using the MySql function, you need to clearly distinguish between two different function libraries, mysqli and mysql.
When using the mysql function library to connect, the required parameters include the host name, user name and password of the MySql server, etc. Additionally, you need to specify the name of the database to which you will connect.
In contrast, the mysqli function library can specify connection properties and options through some parameters. In addition, mysqli functions can cooperate with MySql's stored procedures and triggers, making database operations more flexible and efficient.
4. Use connection pooling
Connection pooling is a technology that can effectively improve the performance of web applications and reduce server overhead. Connection pooling can put multiple database connections into a connection pool so that web applications can reference them when needed.
The benefit of using a connection pool is that it can reduce the overhead of connection creation and can reliably maintain and monitor connections. In addition, connection pooling enables connection reuse, thereby improving the performance of web applications.
Summary
Establishing a closer connection between MySql and PHP requires optimization from many aspects. Using PDO or MySql extension is one of the key steps to achieve this goal. In addition, developers can also use the MySql function library or connection pool to further improve the performance and connection efficiency of web applications. No matter which method you choose, it can help developers establish more effective and stable MySql and PHP connections, thereby building better web applications.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.

SQL commands in MySQL can be divided into categories such as DDL, DML, DQL, DCL, etc., and are used to create, modify, delete databases and tables, insert, update, delete data, and perform complex query operations. 1. Basic usage includes CREATETABLE creation table, INSERTINTO insert data, and SELECT query data. 2. Advanced usage involves JOIN for table joins, subqueries and GROUPBY for data aggregation. 3. Common errors such as syntax errors, data type mismatch and permission problems can be debugged through syntax checking, data type conversion and permission management. 4. Performance optimization suggestions include using indexes, avoiding full table scanning, optimizing JOIN operations and using transactions to ensure data consistency.

InnoDB achieves atomicity through undolog, consistency and isolation through locking mechanism and MVCC, and persistence through redolog. 1) Atomicity: Use undolog to record the original data to ensure that the transaction can be rolled back. 2) Consistency: Ensure the data consistency through row-level locking and MVCC. 3) Isolation: Supports multiple isolation levels, and REPEATABLEREAD is used by default. 4) Persistence: Use redolog to record modifications to ensure that data is saved for a long time.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
