.mo file support in CodeIgniter

Alright i solved my issue. So what helped me alot was https://stackoverflow.com/questions/1949...le-locales this MoParser class.

I have set up a little helper that is linked to service which has a MoParser Factory attached (so to save memory).

Here's the helper:

PHP Code:

if (! function_exists('l'))
{
    /**
    * Returns language from .mo or default CodeIngiter lang.php file.
    * @method l
    * @param  string $index CodeIgniter language_key.
    * @return string Output text.
    */
    function l(string $index):string
    {
        # Take codeigniter locale.
        $ci_locale = service('language')->getLocale();

        # Directory separator & Vendor.
        $DS = DIRECTORY_SEPARATOR;
        $VENDOR = 'vendor' . $DS . 'myname';

        # Language containing folder.
        $LANG = 'Language';

        # Find .mo file with the name of '$ci_locale'
        # in given directory.

        # Request call body and path from debug backtrace.
        $call_body = array_search(__FUNCTION__, array_column(debug_backtrace(), 'function'));
        $call_path = debug_backtrace()[$call_body]['file'];

        # Check vendor position in call_path.
        $vendor_position = strpos(strtolower($call_path), $VENDOR);

        # Check if call is going trough vendor path.
        $language_path = ($vendor_position)
            # Check vendor language path.
            ? substr($call_path, 0, $vendor_position + strlen($VENDOR)) . $DS . 'src' . $DS . $LANG

            # Check application language path.
            : $language_path = APPPATH . $LANG ;

        # Proposed mo file.
        $mo_file = $language_path . $DS . $ci_locale . '.mo';

        # Original Codeigniter Language_value.
        $language_value = lang($index);

        # Check if .mo file exists.
        if (file_exists($language_path)
        && is_dir($language_path)
        && file_exists($language_path . $DS . $ci_locale . '.mo')
        ) {
            # Bind with language.
            return service('lang')->mo($mo_file, $ci_locale)->take($language_value);
        }

        # No .mo? Pass CodeIgniter default.
        return $language_value;
    }
} 


And this is the .mo file factory which is called by the helper to return translations.

PHP Code:

<?php

namespace MyName\MyPackage\Models;

use MyName\MyPackage\Libraries\MoParser;

class Mo extends MoParser
{
    /**
    * Loaded mo file.
    */
    protected array $mo;

    /**
    * Mo factory construction by file and locale.
    * @method __construct
    * @param  string $mo_file Complete path to file.
    * @param  string $locale language locale.
    */
    public function __construct(public string $mo_file, public string $locale = 'en')
    {
        # Load mo file.
        $this->mo = $this->loadTranslationData($mo_file, $locale);
    }

    /**
    * Retrieves translation from MO or returns original.
    * @method take
    * @param  string $language_value input search value.
    * @return mixed translation or original.
    */
    public function take(string $language_value):mixed
    {
        # Check locale.
        if (array_key_exists($this->locale, $this->mo))
        {
            # Check Mo.
            return (array_key_exists($language_value, $this->mo[$this->locale]))
                # Return translation.
                ? $this->mo[$this->locale][$language_value]

                # Return original.
                : $language_value ;
        }
    }
} 


Hope these snippets help anyone stuck with including .mo files!
