Php Error Reporting Not Working
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";".

Error Settings Error settings in php.ini tell PHP interpreter what kind of errors should be reported and where those should be reported. You may enable these settings in your development environment and disable few in your production environment http://www.phpknowhow.com/configuration/php-ini-error-settings/ since useful information error reports provide can also be sensitive information that outsiders shouldn't see. display_errors Default value of this setting is ‘On'. It tells PHP interpreter that if it finds a type of error http://schoolsofweb.com/how-to-enable-php-error-reporting-using-php-ini/ mentioned in error_reporting setting then add it to the output of the script. This basically means to show the errors in web browser. display_startup_errors Default value of this setting is ‘Off'. This tells whether to display php error errors that occur in PHP's startup sequence. PHP manual recommends turning this ‘On' only in your development environment as an aid for debugging. log_errors Default value of this setting is ‘Off'. This setting tells whether errors should be logged in web server's error log file. When you finish your application and put it live, it's a good practice that you turn ‘Off' display_errors and turn ‘On' log_errors in your production server's php error reporting php.ini file. This prevents users seeing any sensitive information that can go with error reports and let you still see them via web server's error log. But in development, you would rather like to see errors on the web browser and would set the settings other way around. error_reporting This setting tells what type of errors should be displayed and/or logged. There are constants that can be given as values to this setting and there is single constant (E_ALL) that represents all error types. Default value of this setting will be like below. error_reporting = E_ALL & ~E_NOTICE Above it instructs to discard errors fall into notices category. For an example, if you used an undefined variable in an echo() statement, PHP generates a notice. This can be a useful feature in debugging. Think that you defined a variable as $name but mistyped it in the echo() statement as $nmae then PHP interpreter would let you know it. So, make sure you enable notices in your development environment by using just E_ALL as below. error_reporting = E_ALL E_STRICT was introduced in PHP 5.0.0 and till PHP 5.4.0, it was not included in E_ALL. So, if you are using a version in-between, have the error_reporting setting as below in your development enviro
