We typically don't think of numbers in this way, but mathematicians need to because there's number systems other than base 10. The location of PHP's ini file is set when PHP is compiled (it'd be pretty hard to have an ini setting for the location of php.ini, no?). Php Error Handling Best Practices Custom error handlers are used to create customized error output.

Each try must have at least one corresponding catch block. A caught exception won't interact with the PHP error system at all. Set Error Handler The default error handler for PHP is the built in error handler. The default value is: “E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED,” meaning this setting does not show E_NOTICE, E_STRICT and E_DEPRECATED level errors.
