Missing function locale_set_default(...) in Codeigniter 4

[Ansulsingkang]

try to change in /system/Codeignater.php line 184
locale_set_default($this->config->defaultLocale ?? 'en');

become:

if( function_exists('locale_set_default' ) ) :
    locale_set_default($this->config->defaultLocale ?? 'en');
    endif;

That is a hack and won't be accepted. Please install intl and its dependencies for the function to work.

Can you show us how to install it in cpanel?

You should ask your cpanel provider if intl is installed. Then in your custom php.ini add the line extension=intl.
