PHP错误按需报告

Question

In PHP how do you make it so that it will only display errors when using the error_reporting() function. Currently the IIS PHP application is set to 'Production machine'. If I change it to Development machine it will print out all errors even without error_reporting().

Answer 1

error_reporting may be set by your application and override the php.ini setting.

In any case, you should never turn it off.

Instead, change display_errors to Off in php.ini, or in your code:

ini_set('display_errors', 0);

Answer 2

On your "Production machine" you can toggle the error_reporting on and off... directly in your PHP script.

You can also find this in your php.ini file on your server to set the default.

<?php

// Turn off all error reporting
error_reporting(0);

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);

// Report all PHP errors (see changelog)
error_reporting(E_ALL);

// Report all PHP errors
error_reporting(-1);

?>

Answer 3

我得到了想要使用的行为：

error_reporting(E_ALL); ini_set('display_errors', 1);

Answer 4

Do

error_reporting(0);

work for you?
