PHP turn on and off error tips

There are two ways to open and close the PHP error prompt, one in the php.ini configuration file. The other is the use of function Ini_set () and error_reporting () settings in PHP files.

1. Find the display_errors in php.ini, set the error prompt to turn on and off, off and on. Setting the Error_reporting value also represents the wrong level.

Some common values

E_all (Show all errors, warnings and notices including coding.) All errors
E_all & ~e_notice (Show all errors, except for notices) except notification, all errors
2. If you cannot modify the php.ini file, PHP also provides the relevant functions to dynamically configure.

Ini_set (' display_errors ', ' off '), turning off error prompts.

Ini_set (' display_errors ', ' on '); Open the error prompt.

Error_reporting (E_all & ~e_notice) sets the error level.

Some common frameworks, or CMS systems, use these two functions to control the display of PHP errors.

Implementation in micro-engine

Define (' DEVELOPMENT ', $_w[' config '] [' setting '] [' DEVELOPMENT '] = = 1);
if (DEVELOPMENT) {
Ini_set (' display_errors ', ' 1 ');
Error_reporting (e_all ^ e_notice);
} else {
error_reporting (0);
}
