error_reporting()函数用法,errorreporting
首先要知道error_reporting()函数是用来设置错误级别并返回当前级别的。它有14个错误级别,如下:
1 E_ERROR 致命的运行时错误。 错误无法恢复过来。脚本的执行被暂停
2 E_WARNING 非致命的运行时错误。 脚本的执行不会停止
4 E_PARSE 编译时解析错误。解析错误应该只由分析器生成
8 E_NOTICE 运行时间的通知。
16 E_CORE_ERROR 在PHP启动时的致命错误。这就好比一个在PHP核心的E_ERROR
32 E_CORE_WARNING 在PHP启动时的非致命的错误。这就好比一个在PHP核心E_WARNING警告
64 E_COMPILE_ERROR 致命的编译时错误。 这就像由Zend脚本引擎生成了一个E_ERROR
128 E_COMPILE_WARNING 非致命的编译时错误,由Zend脚本引擎生成了一个E_WARNING警告
256 E_USER_ERROR 致命的用户生成的错误。
512 E_USER_WARNING 非致命的用户生成的警告。
1024 E_USER_NOTICE 用户生成的通知。
2048 E_STRICT 运行时间的通知。
4096 E_RECOVERABLE_ERROR 捕捉致命的错误。
8191 E_ALL来 所有的错误和警告。
好像php默认是不开启错误的,所以你需要配置php.ini文件:
将 display_errors = Off 改为display_errors = On
另外还要配置错误级别:将
error_reporting = E_ALL 改为:
error_reporting = E_ALL & ~E_NOTICE
应为php默认是显示所有错误的,而有些无害的提示我们不需要显示,所以设置如上!
也可以在php代码运用如下:
- php
- //禁用错误报告,也就是不显示错误
- error_reporting(0);
- //报告运行时错误
- error_reporting(E_ERROR | E_WARNING | E_PARSE);
- //报告所有错误
- error_reporting(E_ALL);
- ?>

Go language provides two dynamic function creation technologies: closure and reflection. closures allow access to variables within the closure scope, and reflection can create new functions using the FuncOf function. These technologies are useful in customizing HTTP routers, implementing highly customizable systems, and building pluggable components.

In C++ function naming, it is crucial to consider parameter order to improve readability, reduce errors, and facilitate refactoring. Common parameter order conventions include: action-object, object-action, semantic meaning, and standard library compliance. The optimal order depends on the purpose of the function, parameter types, potential confusion, and language conventions.

The key to writing efficient and maintainable Java functions is: keep it simple. Use meaningful naming. Handle special situations. Use appropriate visibility.

1. The SUM function is used to sum the numbers in a column or a group of cells, for example: =SUM(A1:J10). 2. The AVERAGE function is used to calculate the average of the numbers in a column or a group of cells, for example: =AVERAGE(A1:A10). 3. COUNT function, used to count the number of numbers or text in a column or a group of cells, for example: =COUNT(A1:A10) 4. IF function, used to make logical judgments based on specified conditions and return the corresponding result.

The advantages of default parameters in C++ functions include simplifying calls, enhancing readability, and avoiding errors. The disadvantages are limited flexibility and naming restrictions. Advantages of variadic parameters include unlimited flexibility and dynamic binding. Disadvantages include greater complexity, implicit type conversions, and difficulty in debugging.

The benefits of functions returning reference types in C++ include: Performance improvements: Passing by reference avoids object copying, thus saving memory and time. Direct modification: The caller can directly modify the returned reference object without reassigning it. Code simplicity: Passing by reference simplifies the code and requires no additional assignment operations.

The difference between custom PHP functions and predefined functions is: Scope: Custom functions are limited to the scope of their definition, while predefined functions are accessible throughout the script. How to define: Custom functions are defined using the function keyword, while predefined functions are defined by the PHP kernel. Parameter passing: Custom functions receive parameters, while predefined functions may not require parameters. Extensibility: Custom functions can be created as needed, while predefined functions are built-in and cannot be modified.

Reference parameters in C++ functions (essentially variable aliases, modifying the reference modifies the original variable) and pointer parameters (storing the memory address of the original variable, modifying the variable by dereferencing the pointer) have different usages when passing and modifying variables. Reference parameters are often used to modify original variables (especially large structures) to avoid copy overhead when passed to constructors or assignment operators. Pointer parameters are used to flexibly point to memory locations, implement dynamic data structures, or pass null pointers to represent optional parameters.
