What is PDO? Characteristics of PDO and how to install PDO What is PDO? PDO is the abbreviation of PHP Date Object (PHP Data Object). It is released together with PHP5.1 version. Currently supported databases include Firebird, FreeTDS, Interbase, MySQL, MS SQL Server, ODBC, Oracle, Postgre SQL, SQLite and Sybase, etc., with PDO, users no longer need to use mysql_* functions, aco_* functions or mssql_* functions, nor do they need to encapsulate them into database operation classes. They only need to use the methods in the PDO interface to perform operations on different databases. Operation, when selecting a different database, you only need to modify the DNS (database name) of PDO. In PHP 6, PDO is used to connect to the database by default. All non-PDO extensions will be removed in PHP 6. This extension provides PHP built-in class PDO to access the database. Different databases use the same method name to solve the problem of data

3. Brief introduction to the application of ODBC and JDBC in the database
Introduction: A few days ago, in order to use PowerDesigner reverse engineering to obtain the ER diagram of the data table, I used ODBC. Let me summarize it here. I am not sure about other systems. Windows 7 does not have its own mysql to odbc. To implement, you need to install a mysqlconnectorodbc yourself. The following is how to configure the ODBC data source to connect to mysql.

Using Python to perform SQLite database operations
##Introduction: QLite database is a very small embedded open source database software, which means there is no independent maintenance process, and all maintenance comes from the program itself. It is a relational database management system that complies with ACID. Its design target is embedded, and it has been used in many embedded products. It occupies very low resources. In embedded devices, it may only require a few One hundred K of memory is enough. It can support mainstream operating systems such as Windows/Linux/Unix, and can be combined with many programming languages, such as Tcl, C#, PHP, Java, etc., as well as ODBC interfaces. It is also compared to the two open source worlds of Mysql and PostgreSQL. Famous database

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
