More On Error Reporting in php

Error Reporting

This is a tutorial for Error reporting. Let’s Back to php.ini file(ScreenShot1).

Screenshot1

Error Reporting value is E_All, So we are Reporting errors back to our self as we developing. What happen if i want to report errors Strict errors. Now E_Errors Does not Include E_Strict, So i will specify under error_reporting another value E_Strict (ScreenShot2).

Screenshot2

error_reporting = E_ALL & E_STRICT

Now this will include errors of run-time notices, enable to have PHP suggest changes to your code which will ensure the best interchangeability and forward compatibility of your code. So basically giving us messages about code itself other then errors that you made be coming across  Now “&” sign is use for including and for not including “~” sign is used. (Screenshot3).

Screenshot3

error_reporting = E_All & ~E_NOTICE 

If we don’t wanna Show E_NOTICE types of error we include “~”.This will show all errors, except for notice and coding standards warnings.So Its upto you what level errors you want to display if your codes having errors.If your application is big you can turn onhave a look. Now when u complete your program or applicationon web-server you have to turn error_reporting off
When u complete your program you need to :-

error_reporting=0;

Why the reason being is the errors shows on your pages specially in E_STRICT notices you don’t want to your users or viewers to tell about your errors notices and warnings. For security reasons also u had to turn off. For example if u including file or copying file and there u had errors its shows errors to visitors and they will understand your website structure.So, Best thing is to you put error_reporting=0 when u release your website to web-server to visitors. Now if u had paid hosting you will not have access to php.ini files for that there are some functions have look. What happen if we want to dynamically update error_reporting value inside php (Screenshot4), and (Screenshot5).
