Proposal to Combine Constants - John_Betong - 10-06-2021

PHP now allows array Constants which could group current defines:

Code:
// Works as of PHP 7

define('ANIMALS', array(

    'dog',

    'cat',

    'bird'

));

echo ANIMALS[1]; // outputs "cat"

Sorry, what do you propose?

I think he means to use the new array constants for the defines in CodeIgniter 4

Also maybe the app/Config/Constants.php defines.

That would work if data are meant to be arrays. However, if several items are grouped as arrays for the sake of utilizing array constants, I don't think it is worth the effort.

Imagine combining all the error code constants (EXIT_ERROR, EXIT_AUTO_MIN, EXIT_AUTO_MAX, etc.) to an array constant EXIT_CODES. So which one would you prefer to use the error exit code, EXIT_ERROR or EXIT_CODES[0] ?

I have four sites sites (soon to be more) all calling a common CI4 application and find the following ideal for displaying the relevant constants for each domain:

file: /app/Views/incs/QQQ.php

Code:
 
<?php declare(strict_types=1);

$CI_VERSION = \CodeIgniter\CodeIgniter::CI_VERSION ;

define('QQQ', [

  'memory_get_usage()'      => number_format((float)memory_get_usage()) .' bytes',

  'memory_get_peak_usage()' => number_format(memory_get_peak_usage()).' bytes',

  'date("h:i:s")'  => date('l, jS F Y -H:i:s'),

  'base_url()'      => base_url(),

  'CI_DEBUG'        => CI_DEBUG    ? 'TRUE' : 'FALSE',  

  'APPPATH'        => APPPATH,

  'BASEURL'        => BASEURL,  

  'CI_VERSION'      => $CI_VERSION,  

  'ENVIRONMENT'    => ENVIRONMENT,  

 'CI_ERROR_LOG'    => CI_ERROR_LOG,

  'FCPATH'          => FCPATH,

  'LOCALHOST'      => LOCALHOST,

  'ROOTPATH'        => ROOTPATH,

  'SYSTEMPATH'      => SYSTEMPATH,

  'TESTPATH'        => TESTPATH,

  'WRITEPATH'      => WRITEPATH,

]);

# LOCALHOST defined in index.php

if(LOCALHOST) :

# Maybe rendered in footer.php

echo tabulate((array) QQQ, $title='Table: QQQ');  

endif;

I thought the grouping may be useful instead of separate Constants?
