In the development of PHP language, exception handling is a very important aspect. Exception handling can help developers discover errors in programs in time and handle these errors in a timely manner to avoid program crashes or unpredictable consequences. In this article, we will introduce you to 99 exception handling skills in PHP language development, hoping to help you develop PHP language more effectively.
- Exceptions are predictable errors in a program that need to be handled by developers.
- In the PHP language, exception handling is implemented by using the try-catch statement.
- Throwing an exception through the throw statement can interrupt the program and jump to the specified catch block.
- catch block can catch and handle exceptions and execute corresponding code.
- Never use the exit statement in a catch block to exit the program. Instead, use a more elegant way to handle it.
- During the development process, different exception classes should be defined according to different error types.
- You can inherit the Exception class to define your own exception class.
- Custom exception classes can be used to better manage and handle exceptions.
- Before catching exceptions, you should first judge possible situations to avoid unnecessary exceptions being thrown.
- Using the try-catch-finally statement block can ensure that the code in the finally block will be executed regardless of whether an exception is thrown.
- You can use the set_exception_handler function to set the global exception handling function to handle all exceptions that are not caught by the try-catch block.
- You can use the set_error_handler function to set the global error handling function to handle all errors that are not caught by the try-catch block.
- Global exception handling functions and global error handling functions can record exception and error information in the Log to facilitate developer troubleshooting.
- Using logging can better track and understand the running status of the program, so as to better troubleshoot problems.
- To avoid throwing exceptions repeatedly, you should check before throwing exceptions.
- The type of exception should be specified as much as possible to avoid general exception types from overwriting other exception information.
- Use the throw new Exception() statement to throw an undefined exception, and use the throw new RuntimeException() statement to throw an unchecked exception.
- When defining an exception handler, you should pay attention to defining the scenarios and handling methods for throwing exceptions.
- Use the try-catch statement block to capture and handle all errors and exceptions in PHP.
- Pushdown exception handlers can make code clearer and easier to manage.
- When handling an exception, the exception information should be recorded first, and then the exception should be handled.
- When an exception is thrown, an error description should be specified to facilitate developer troubleshooting.
- During the development process, the use of global variables should be avoided as much as possible to avoid adverse effects on the program.
- Using exception handlers can avoid using return statements, thereby reducing the chance of unpredictable consequences.
- Using exception throwing can reduce the number of jump nesting levels of the code, making the code clearer and easier to maintain.
- Reasonable use of error handling functions can avoid unnecessary exception throwing.
- Use the error handling function to maintain the program running status when an error occurs and provide appropriate options for processing.
- Use the try-catch statement block to capture and handle unknown errors and exceptions that may occur in the program.
- When handling exceptions, you should always maintain the consistency of the program code and avoid using different handling methods in different situations.
- Using the try-catch-finally statement block can ensure that the program can execute normally under all circumstances.
- When handling exceptions, you should choose the appropriate exception type according to the specific situation to avoid confusing exception and error types.
- Use the try-catch statement block to handle all exceptions and errors that occur in the program.

- When using a PHP class, you should fill in the necessary parameters according to the specific conditions of the class to avoid the lack of necessary parameters.
- When handling exceptions, error throwing, catching, processing and release should be followed to avoid exception stack problems.
- When using try-catch statement blocks, you should ensure that the code in the catch block can handle exceptions correctly.
- When handling exceptions, the duration of the exception should be considered to avoid problems during handling.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
