PHP错误提示的关闭方法详解

php under code closure Method join in copy hint method of program Detailed explanation mistake

最简单的办法就是直接在php程序代码中加入下面代码:

复制代码 代码如下:

error_reporting(E_ALL^E_NOTICE^E_WARNING);

可以关闭所有notice 和 warning 级别的错误。

把这个语句放在您脚本的功用包含文件中,通常为config.php 或者conn.php 中就可以控制输出了。

当然我也也可以在php.ini中进行设置了方法如下

打开PHP安装目录下的php.ini文件

找到display_errors = On 修改为 display_errors = off

注意:如果你已经把PHP.ini文件复制到windows目录下,那么必须同时把c:windows/php.ini里的display_errors = On 修改为display_errors = off

PHP .ini中display_errors = Off失效的解决

问题:

PHP 设置文件php .ini中明明已经设置display_errors = Off,但是在运行过程中,网页上还是会出现错误信息。

解决:

打开PHP安装目录下的php.ini文件

找到log_errors = off 修改为 log_errors = on

找到error_log = filename 修改为 error_log="D:PHPerrlogphp_error.log" (这里的目录和文件名D:PHPerrlogphp_error.log随便你取什么)

注意:如果你已经把PHP.ini文件复制到windows目录下,那么必须同时把c:windows/php.ini文件.

此外php_error.log至少要有USER的修改和写权限,否则无法输出错误日志.


经常见到error_reporting(7)直意为:设定错误讯息回报的等级。

value   constant   
  1   E_ERROR     
  2   E_WARNING     
  4   E_PARSE     
  8   E_NOTICE     
  16   E_CORE_ERROR     
  32   E_CORE_WARNING     
  64   E_COMPILE_ERROR     
  128   E_COMPILE_WARNING     
  256   E_USER_ERROR     
  512   E_USER_WARNING     
  1024   E_USER_NOTICE     
  2047   E_ALL     
  2048   E_STRICT 

 然而7=1+2+4
就是出错时显示1 E_ERROR    2 E_WARNING      4 E_PARSE

复制代码 代码如下:


//禁用错误报告
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);
?>

Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
