Enable Php Logging Apache
When building or maintaining a site powered by PHP, errors can happen. These errors can cause issues that are often difficult to php log level pinpoint or accurately troubleshoot without error logging in place. These logs are also useful in cases where a problem is sporadic or difficult to replicate. Instead of spending hours trying to recreate the error, you can https://davidwinter.me/enable-php-error-logging/ check the logs and uncover the issue fairly quickly. In this guide, we will go over a few ways to turn up the logging levels so you can see errors that might not appear in these logs at their default settings. Enabling PHP Error Logging Through htaccess Depending on your hosting provider, you may be able to activate private PHP error logging using the htaccess file. This file acts like a doorman, allowing http://www.rockettheme.com/docs/technical_tips/general/phplogging.md certain traffic through, directing traffic when exceptions are needed, and preventing access to secured areas of your site's file structure to unauthorized parties, and more. If you want to enable private PHP error logging using this file, you will need to add the code below to either your htaccess file, or httpd.conf (a common configuration file found on Apache). php_flag log_errors on php_value error_log /home/path/public_html/(your domain)/PHP_errors.log The last row of the above text should be adjusted to match the actual location of the PHP_errors.log file. If one does not already exist in your site's root directory, you can create it using a text editor. Set the permissions to this file to 755. If required, you can set this file's permission level to 777. Once this is done, you should start seeing error log entries appear in the file, which you can read using a standard text editor like Notepad or TextEdit. Keep in mind that if you do nothing else, this log file may be accessible by the public. Enabling PHP Error Logging Through Apache GUI If you are building your site on a local Apache server, or hosting it from a machine and prefer to use GUI tools, Apache makes it easy to turn on and configure PHP error logging.

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 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.
