php error reporting

/* Answer to: "php error reporting" */

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

/*
  What do these lines of code do exactly?

  The ini_set function will try to override the configuration found
  in your PHP ini file.

  The display_errors and display_startup_errors are just two of the
  directives that are available. The display_errors directive will
  determine if the errors will be displayed or hidden to the user.
  Usually, the dispay_errors directive should be turned off after
  development.

  The display_startup_errors, however, is a separate directive
  because the display_errors doesn’t handle the errors that will be
  encountered during PHP’s startup sequence. The list of the
  directives that can be overridden by the ini_set function is found
  in the official documentation.

php Error Reporting

; This directive controls whether or not and where PHP will output errors,
; notices and warnings too. Error output is very useful during development, but
; it could be very dangerous in production environments. Depending on the code
; which is triggering the error, sensitive information could potentially leak
; out of your application such as database usernames and passwords or worse.
; For production environments, we recommend logging errors rather than
; sending them to STDOUT.
; Possible Values:
;   Off = Do not display any errors
;   stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
;   On or stdout = Display errors to STDOUT
; Default Value: On
; Development Value: On
; Production Value: Off

// how to display php errors on your browser : 
// first step, create an error function : 

$errors = array();

// we want to display an error when the user does not correctly fill, 
// in the 'password' box when registering on your website : 

if(empty($_POST['password']) ||
   $_POST['password'] != $_POST['password_confirm']){
