Detailed explanation of turning off PHP error script prompt_PHP tutorial

 　　最简单的办法就是直接在php程序代码中加入下面代码：

代码如下

error_reporting(E_ALL^E_NOTICE^E_WARNING);

代码如下
error_reporting(E_ALL^E_NOTICE^E_WARNING);

All notice and warning level errors can be turned off.

Put this statement in the function include file of your script, usually config.php or conn.php to control the output.

Of course I can also set it in php.ini as follows

Open the php.ini file in the PHP installation directory

Find display_errors = On and change it to display_errors = off

Note: If you have copied the PHP.ini file to the windows directory, you must also change display_errors = On in c:windows/php.ini to display_errors = off

Solution to the failure of display_errors = Off in PHP .ini

Question:

　Display_errors = Off has been set in the PHP setting file php.ini, but during operation, error messages still appear on the web page.

Solution:

Open the php.ini file in the PHP installation directory

Find log_errors = off and change it to log_errors = on

Find error_log = filename and change it to error_log="D:PHPerrlogphp_error.log" (the directory and file name here D:PHPerrlogphp_error.log are whatever you want)

Note: If you have copied the PHP.ini file to the windows directory, you must also copy the c:windows/php.ini file.

In addition, php_error.log must have at least the modification and write permissions of USER, otherwise the error log cannot be output.

It is often seen that error_reporting(7) means: setting the level of error message reporting.

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

However, 7=1+2+4

　When an error occurs, 1 E_ERROR 2 E_WARNING 4 E_PARSE is displayed

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); ?>
