them; 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 http://www.w3schools.com/Php/func_error_reporting.asp E_ALL. I 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 http://stackoverflow.com/questions/1053424/how-do-i-get-php-errors-to-display 9 at 7:16 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

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 php error notices 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 3,67183982 asked May 10 '09 at 9:48 Candidasa 2,95982330 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 355 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_
plugin/theme developer should know about these so that they may fix them in a future release). PHP warnings and notices are nothing to worry about on a production site most of the time. Some of these can even be generated because the developer has to keep compatibility with older versions of WordPress as well as older PHP versions. The solution: If you simply set WP_DEBUG to false in your wp-config.php file you should be fine. These don’t affect your site in any way. However, the problem is that some times the above does not work. That can happen most times on cheap shared hosts that force displaying PHP warnings and notices. In that case, you can replace this line from your wp-config.php file: define('WP_DEBUG', false); with this: ini_set('log_errors','On'); ini_set('display_errors','Off'); ini_set('error_reporting', E_ALL ); define('WP_DEBUG', false); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false); I hope that helps someone out there! twitter Written by Blog Logo Aristeides Stathopoulos Published 03 Oct 2014 Supported by Proudly published with Jekyll You should subscribe to my feed.
