Remove warning, notice and other information from the php page

error_reporting Setting the error message reporting level

2047 I remember it should be E_ALL.

There are many configuration settings in the php.ini file. You should have set up your php.ini file and placed it in the appropriate directory, as documented in the instructions for installing PHP and Apache 2 on Linux (see Resources). When debugging PHP applications, there are two configuration variables that you should be aware of. Here are the two variables and their default values:

display_errors = Off
error_reporting = E_ALL

E_ALL can tell you everything from bad coding practices to harmless tips to errors. E_ALL is a bit too detailed for the development process, because it also displays prompts on the screen for small things (such as variables not being initialized), which will mess up the browser's output

So it is not recommended to use 2047, it is better to The default value is changed to: error_reporting = E_ALL & ~E_NOTICE

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

:

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

Solution:

After checking log_errors=On, according to the official statement, when this log_errors is set to On, then the error_log file must be specified. If it is not specified or the specified file does not have permission to write, Then it will still be output to the normal output channel, which will invalidate the specified Off of display_errors, and the error message will still be printed. So set log_errors = Off and the problem is solved.

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

means that when an error occurs, 1 E_ERROR 2 E_WARNING is displayed 4 E_PARSE

<?php
//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); 
?>

Question:

Can I turn off PHP error prompts? I don't want others to see the errors in my program.

Answer:

Since the settings in PHP.ini are global, we cannot directly modify the global configuration information for an individual user, but you can adjust it through the error_reporting PHP function The error message output of the script you run, for example:

error_reporting(E_ALL^E_NOTICE^E_WARNING);

can turn off all notice and warning level errors.

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