Turning on error reporting in PHP The php.ini file is set default configuration values. display_errors = Off Error_reporting = E_ALL The display_errors variable tells PHP whether or not to display errors. Simply change the value to “On” when developing a PHP program. Error_reporting with an “E_ALL” value tells the server to display everything - from harmless warnings to bad coding practices, to actual coding errors. If you only want to display the “bad coding practices” warnings and the actual errors, but not those harmless coding notices, you can set Error_reporting value to E_ALL & ~E_NOTICE. Ideally the error reporting settings should be: display_errors = ON error_reporting = E_ALL & ~E_NOTICE For the changes to take effect, restart APACHE. Enabling server-level error reporting There are times when turning on error reporting in PHP may not work as you may have multiple versions of PHP installed in your computer. It is possible that APACHE is not recognizing the recently configured php.ini file as it

only takes a minute: Sign up How do I get PHP Errors to display? up vote 679 down vote favorite 204 I have checked my PHP ini file and display errors is set and also error reporting is E_ALL. I http://www.hiddenwebgenius.com/blog/web-development/basic-php-error-reporting-techniques/ have 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 http://stackoverflow.com/questions/1053424/how-do-i-get-php-errors-to-display Maninderpreet Singh 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_erro

the top line there, and add the rest to your wp-config.php file to get more detailed error reporting from your WordPress site. Definitely don't do this live, do it for local development and testing. // define('WP_DEBUG', false); define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false); @ini_set('display_errors', 0); Comments Rakshit Permalink to comment# February 9, 2012 Nice one Chris. Thanks. Reply ↓ geopaL Permalink to comment# February 9, 2012 for a live website I would recommend: define('WP_DEBUG', false); @ini_set('log_errors','On'); @ini_set('display_errors','Off'); @ini_set('error_log','phperrors.log'); // path to server-writable log file don't forget to drop a phperrors.log file inside your remote directory with write permissions Reply ↓ Willem-Siebe Spoelstra Permalink to comment# September 29, 2015 What does make you code any different then: define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false); ? Diego Permalink to comment# January 13, 2016 Thanks @geopaL! I have the same question as @Willem-Siebe Spoelstra does. Why do you recommend that code instead of using the WordPress constants WP_DEBUG, WP_DEBUG_LOG and WP_DEBUG_DISPLAY? I know they are meant for local testing and staging installs but…what are the advantages of the code you have provided? Is it for performance reasons? The only thing that comes into my mind is the fact that Enabling WP_DEBUG will consume extra system resources trying to detect deprecated WordPress functions and arguments that are being used. Thanks! sagalbot Permalink to comment# May 18, 2012 Not sure where the errors get reported to with this turned on.. is there a log file somewhere? Reply ↓ sagalbot Permalink to comment# May 18, 2012 Answered my own question on the codex. /** * This will log all errors notices and warnings to a file called debug.log in * wp-content (if Apache does not have write permission, you may need to create * the file first and set the appropriate permissions (i.e. use 666) ) */ define(‘WP_DEBUG', true); define(‘WP_DEBUG_LOG', true); define(‘WP_DEBUG_DISPLAY', false); @ini_set(‘display_errors',0); Alice Permalink to comment# September 22, 2013 I need your help when I log in my dashboard is a blank page.
