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:

 

    1. php
    2. //禁用错误报告,也就是不显示错误
    3. error_reporting(0);
    4. //报告运行时错误
    5. error_reporting(E_ERROR | E_WARNING | E_PARSE);
    6. //报告所有错误
    7. error_reporting(E_ALL);
    8. ?>

Tips for dynamically creating new functions in golang functions Tips for dynamically creating new functions in golang functions Apr 25, 2024 pm 02:39 PM

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.

Considerations for parameter order in C++ function naming Considerations for parameter order in C++ function naming Apr 24, 2024 pm 04:21 PM

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.

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.

Comparison of the advantages and disadvantages of C++ function default parameters and variable parameters Comparison of the advantages and disadvantages of C++ function default parameters and variable parameters Apr 21, 2024 am 10:21 AM

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.

What are the benefits of C++ functions returning reference types? What are the benefits of C++ functions returning reference types? Apr 20, 2024 pm 09:12 PM

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.

What is the difference between custom PHP functions and predefined functions? What is the difference between custom PHP functions and predefined functions? Apr 22, 2024 pm 02:21 PM

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.

Advanced usage of reference parameters and pointer parameters in C++ functions Advanced usage of reference parameters and pointer parameters in C++ functions Apr 21, 2024 am 09:39 AM

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.
