Php Display_errors
in PHP quite frustrating. Quite often I will try and run the script and just get a blank screen back. No error message, just empty screen. The cause might have been a simple syntax error (wrong bracket, missing semicolon), or a failed function call, or something else entirely. It is very difficult to figure out what went wrong. I end up commenting out code, entering "echo" statements everywhere, etc. trying to narrow php error types down the problem. But there surely must be a better way, right?. So, is there a way to get PHP to produce useful error message like Java does? Can anyone recommend good PHP debugging tips, tools and techniques? php debugging error-handling share|improve this question edited May 11 '13 at 23:52 hkBattousai 3,66683982 asked May 10 '09 at 9:48 Candidasa 2,94982330 coding.smashingmagazine.com/2011/11/30/… –Alex Jul 15 '12 at 14:54 1 Also see stackoverflow.com/q/1475297/632951 –Pacerier Oct 14 '14 at 9:37 @JuannStrauss, That's understating it. And when you finally see the errors, it says T_PAAMAYIM_NEKUDOTAYIM. Or maybe "must be an instance of integer, integer given". –Pacerier Apr 3 '15 at 20:02 Tutorial on this: code2real.blogspot.com/2015/06/… –Pupil Sep 9 '15 at 7:21 add a comment| 27 Answers 27 active oldest votes up vote 354 down vote accepted For syntax errors, you need to enable error display in the php.ini. By default these are turned off because you don't want a "customer" seeing the error messages. Check this page in the PHP documentation for information on the 2 directives: error_reporting and display_errors. display_errors is probably the one you want to change. If you can't modify the php.ini, you can also add the following lines to an .htaccess file: php_flag display_errors on php_value err
reporting technology introduced by Microsoft with WindowsXP[1] and included in later Windows versions and Windows Mobile 5.0 and 6.0. Not to be confused with the Dr. Watson debugging tool which left the memory dump on php verbose command line the user's local machine, Windows Error Reporting collects and offers to send post-error

debug information (a memory dump) using the Internet to the Microsoft or stops responding on a user's desktop. No data

is sent without the user's consent.[2] When a dump (or other error signature information) reaches the Microsoft server, it is analyzed and a solution is sent back to the user when one is available. http://stackoverflow.com/questions/845021/how-to-get-useful-error-messages-in-php Solutions are served using Windows Error Reporting Responses. Windows Error Reporting runs as a Windows service and can optionally be entirely disabled. If Windows Error Reporting itself crashes, then an error report that the original crashed process produced cannot be sent at all. Kinshuman is the original designer of Windows Error Reporting in Vista which is the same design and implementation that is present in current Windows https://en.wikipedia.org/wiki/Windows_Error_Reporting versions. [3] Contents 1 History 1.1 Windows XP 1.2 Windows Vista 1.3 Windows 7 1.4 Windows 8 2 System design 2.1 Buckets 3 Third-party software 4 Impact on future software 5 Privacy concerns and use by the NSA 6 Alternatives 7 See also 8 References History[edit] Windows XP[edit] Microsoft first introduced Windows Error Reporting with WindowsXP.[1] Windows Vista[edit] Windows Error Reporting was improved significantly in WindowsVista. Most importantly a new set of public APIs have been created for reporting failures other than application crashes and hangs.[4] Developers can create custom reports and customize the reporting user interface. The new APIs are documented in MSDN. The architecture of Windows Error Reporting has been revamped with a focus on reliability and user experience. WER can now report errors even when the process is in a very bad state for example if the process has encountered stack exhaustions, PEB/TEB corruptions, heap corruptions, etc. In earlier OSs prior to WindowsVista, the process usually terminated silently without generating an error report in these conditions. A new Control Panel applet, "Problem Reports and Solutions" was also introduced, keeping a record of system and application errors and issues, as well as presenting probable solutions to prob

When should I enable debug mode? Reporting issues in forums, or requesting assistance Debugging There are php error several things that can cause errors on your site. Before requesting assistance in the forums, it is helpful to understand and them and attempt to narrow down the issue. Cannot Login Turn debug mode on and also check /path/to/getsimple/data/other/logs/errorlog.txt for errors Report these in forums, make note of any recent changes and plugins in use especially user related php error reporting ones, like ktblock and multi users. White Screen with no output This is commonly referred to as PHP white screen of death. It typically occurs when php error reporting is off, but can occur even when it is on. This is usually the result of a fatal php compile error, eg. missing function, missing required file, or a syntax error etc. The best way to check this is to enable debugmode in gsconfig and check for output again. PHP will throw errors with details that may even include the file and line number the error occurs on. As you can imagine this greatly helps troubleshoot these issues. To turn on debugging, uncomment the GSDEBUG line in /path/to/getsimple/gsconfig.php to enable full PHP errors output to help debug in your browser. All PHP errors are also written to a log,regardless of the GSDEBUG setting, check /path/to/getsimple/data/other/logs/errorlog.txt 500 error in browser This can also be caused by a fatal or compile fail PHP error, checking the errorlog is typically required here as no output will be avail
