restarted my apache web server. I have even put these lines at the top of my script and it doesn't even catch simple parse errors. For example, I declare variables with a "$" and I don't close statements";". But all my scripts show a blank page on these errors, but i want to actually see the errors in my browser output. error_reporting(E_ALL); ini_set('display_errors', 1); What is left to do? php error-reporting share|improve this question edited Mar 9 at 7:16 Maninderpreet Singh php hide errors 1,7111524 asked Jun 27 '09 at 19:09 Abs 13.4k68209356 3 I've yet to nail down exactly why this works sometimes and not others, but for anyone wanting to quickly toggle errors in a php script (or enable them via a $_REQUEST parameter) these two lines will work most of the time. –brandonscript Oct 28 '13 at 20:15 well you can see details of the error by enabling xdebug from php ini file. –jewelhuq Jan 13 at 10:14 add a comment| 13 Answers 13 active oldest votes up vote 1359 down vote accepted This always works for me: ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); However, this doesn't make PHP to show parse errors - the only way to show those errors is to modify your php.ini with this line: display_errors = on share|improve this answer edited Oct 23 '15 at 12:24 tleb 1,173721 answered Jan 29 '14 at 11:25 Fancy John 14k2915 4 why is this not the best answer? –özg Jul 4 '14 at 11:52 13 @özg Because this configuration doesn't show parser errors (errors due to syntactically incorrect scripts --e.g: ill-formed scripts). The Zend parser (the one used by php) is executed before the script is executed. So, if the script has syntactic errors, these ini_set directives are never executed and every existing syntactic error is never displayed; only logged. If you want to show syntactic errors, you have to set display_errors and error_reporting di

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 in the echo() statement as $nmae then PHP interpreter would let you know it. So, make sure you enable notices in your development environment by using just E_ALL as below. error_reporting = E_ALL
