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 http://stackoverflow.com/questions/845021/how-to-get-useful-error-messages-in-php code, entering "echo" statements everywhere, etc. trying to narrow 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 3,66183982 asked May 10 '09 at 9:48 Candidasa 2,94482330 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 352 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 modi

Error Settings Error settings in php.ini tell PHP interpreter what kind of errors should be reported and where those should be reported. You may enable these settings in your development environment and disable few in your production environment since useful information error reports provide can also be sensitive information that outsiders shouldn't see. display_errors Default value of this setting is ‘On'. It tells PHP interpreter that if it finds a type of error mentioned in error_reporting setting then add it to the output of the script. This basically means to show the errors in web browser. display_startup_errors Default value of this setting is ‘Off'. This tells whether to display errors that occur in PHP's startup sequence. PHP manual recommends turning this ‘On' only in your development environment as an aid for debugging. log_errors Default value of this setting is ‘Off'. This setting tells whether errors should be logged in web server's error log file. When you finish your application and put it live, it's a good practice that you turn ‘Off' display_errors and turn ‘On' log_errors in your production server's php.ini file. This prevents users seeing any sensitive information that can go with error reports and let you still see them via web server's error log. But in development, you would rather like to see errors on the web browser and would set the settings other way around. error_reporting This setting tells what type of errors should be displayed and/or logged. There are constants that can be given as values to this setting and there is single constant (E_ALL) that represents all error types. Default value of this setting will be like below. error_reporting = E_ALL & ~E_NOTICE Above it instructs to discard errors fall into notices category. For an example, if you used an undefined variable in an echo() statement, PHP generates a notice. This can be a useful feature in debugging. Think that you defined a variable as $name but mistyped it i
