vote 656 down vote favorite 197 I have checked my PHP ini file and display errors is set and also error reporting is 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 error 0 joomla 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 1,7111524 asked Jun 27 '09 at 19:09 Abs 13.1k68208356 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 1316 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 1,154721 answered Jan 29 '14 at 11:25 Fancy John 13.5k2915 3 why is this not the best answer? –özg

In addition, it creates the $DISPLAY variable which points to this proxy and calls the xauth to install a proxy key 0 display error which authenticates to this X-server proxy on remote machine: # echo "$DISPLAY" localhost:11.0 # xauth list | grep 11 A58/unix:11 MIT-MAGIC-COOKIE-1 39324086672d1ae35e373476c3891a77 # However, X clients on remote machine do not start properly: # wireshark (wireshark:10083): Gtk-WARNING **: cannot open display: localhost:11.0 # xterm Warning: This program is an suid-root program or is being run by the root user. The full text of the error or warning message cannot be safely formatted in this environment. You may get a more descriptive message by running the program as a non-root user or by removing the suid bit on the executable. xterm: Xt error: Can't open display: %s # X forwarding doesn't use xhost so at least this can be excluded. I tried to find some useful log entries both on machine where SSH server is running and machine where SSH client is running with find /var/log/ -mmin -5 -type f command, but this did not give any hints. SSH server version is OpenSSH_5.9p1 and SSH client version is OpenSSH_5.2p1.
