python threading timer example
Article Introduction：threading.Timer executes functions asynchronously after a specified delay without blocking the main thread, and is suitable for handling lightweight delays or periodic tasks. ①Basic usage: Create Timer object and call start() method to delay execution of the specified function; ② Cancel task: Calling cancel() method before the task is executed can prevent execution; ③ Repeating execution: Enable periodic operation by encapsulating the RepeatingTimer class; ④ Note: Each Timer starts a new thread, and resources should be managed reasonably. If necessary, call cancel() to avoid memory waste. When the main program exits, you need to pay attention to the influence of non-daemon threads. It is suitable for delayed operations, timeout processing, and simple polling. It is simple but very practical.

PHP Master | Exceptional Exceptions
Article Introduction：Core points
PHP exception is a special class that can be thrown and caught to indicate unexpected events. Unlike unrecoverable errors, exceptions are intended to be processed by the calling code and bubble upward along the execution chain until they are caught.
The difference between PHP errors and exceptions is that the error is irrecoverable and occurs in the main execution loop, indicating that there is a problem with the stability of the code or environment; while the exception is recoverable and may occur outside the main execution loop, and does not indicate the system. Unstable.
Not all non-successful situations require exceptions to be thrown. Exceptions should be thrown only if they really cannot continue execution. This means that an action that is not a normal operation or standard, an abnormality, deviates from normal and expected situations.
