Use exception mode -PDO::ERRMODE_EXCEPTION (Method 3 for capturing errors in SQL statements in PDO) exception mode will create a PDOException and set the erorCode attribute, which can encapsulate the execution code into a try{...}catch In the {...} statement, uncaught exceptions will cause the script to interrupt and display a stack trace to let the user understand where the problem occurred! In the first two articles "Using the default mode-PDO::ERRMODE_SILENT (Method 1 to capture errors in SQL statements in PDO)" and "Using warning mode-PDO::ERRMODE_WARNING (Method 2 to capture errors in SQL statements in PDO)" We have introduced two methods: default mode and exception mode, so today we will introduce the third method to capture errors in SQL statements in PDO ~ Another very useful thing about exception mode is that it can be clearer than traditional PHP style warnings You can easily build your own error handling, and exception mode requires less code/nesting than silent mode and explicitly checking the return value of each database call.

8. Capturing errors in SQL statements in PDO
Introduction: Capturing errors in SQL statements in PDO Error: Use default mode -----PDO::ERRMODE_SILENT sets the errorCode property of the PDOStatement object in default mode, but does nothing else. For example: add data to the database through the prepare() and execute() methods, set the erroCode attribute of the PDOStatement object, and manually detect errors in the code. The steps are as follows. $dbms=mysql;//Database type $dbName=admin;//Database used

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
