takes a minute: Sign up How to get useful error messages in PHP? up vote 369 down vote favorite 168 I find programming in PHP quite frustrating. Quite often I will try and run the script and just get a php error types 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 php hide errors 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.

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_errors on php_value error_reporting 2039 You may want to consider using the value of E_ALL (as mentioned by Gumbo) for your version of PHP for error_reporting to get all of the errors. more info 3 other items: (1) You can check the error log file as it will have all of the errors (unless

I http://stackoverflow.com/questions/845021/how-to-get-useful-error-messages-in-php 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";".

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 an

Overview Error Reporting is a useful Joomla function to troubleshoot PHP errors on your Joomla site. This function provides some clues about what and where the PHP problems are. 2. When to turn it on? Got blank/ white screen in your Joomla site frontend? Well, that calls for turning on the error reporting feature. You may also want to disable the URL rewriting (htaccess method) using Apache mod_rewrite under the SEO settings for differential diagnosis of the issue as url rewriting with htaccess file in non-supported server (mod_rewrite not active) also renders blank pages. 3. How to proceed In your Admin Panel, navigate through Global Configuration >> Server tab >> Error Reporting. Joomla Error Reporting settings There are several options for you to choose, namely: System Default : Joomla will inherit error reporting defaults set in the server (usually in php.ini file). None : Choose this option to switch off the Error Reporting so that no notification will be shown. However, when any 3rd party extension overrides Joomla error reporting with their own settings, notifications may still appear. Simple : Overrides server settings to give a basic report with warnings only about the fatal errors. Error Reporting in Simple settings Maximum (Recommended) : Overrides server settings to gives full report with all the errors, warnings, notices, deprecated functions call, strict standards on the website. Error Reporting in Maximum settings Tip : You can enable the Error Reporting with the configuration.php file. Edit the file and add one of the following numeric values for $error_reporting, which equals to the PHP’s error constants: -1 = 0 : No error reporting. 30711 = E_ALL & ~(E_NOTICE|E_WARNING) : All errors reporting. No warnings or notices. 30711 = E_ALL & ~E_NOTICE : All errors and warnings reporting. No notices. 30719 = E_ALL : All errors, warnings and notices reporting. 327
