Php get list of locales installed on system

On linux , the list of locales installed on the system can be fetched through the terminal command locale -a :

$ locale -a
C
C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
es_AR.utf8
es_BO.utf8
es_CL.utf8
es_CO.utf8
es_CR.utf8
es_DO.utf8
es_EC.utf8
es_ES.utf8
es_GT.utf8
es_HN.utf8

nl_AW
nl_AW.utf8
nl_BE.utf8
nl_NL.utf8
POSIX
si_LK
si_LK.utf8
zh_CN.utf8
zh_SG.utf8

Now this command can be used inside php to get the list. Along with this list we can also add some information like language name and country name using a list of countries and languages.

Here is a list of country codes :

Now the list of locales + countries + languages can be used to present information properly. Here is the code :

$locale_data = array();
		
//Get locales from Linux terminal command locale
$locales = shell_exec('locale -a');

$locales = explode("n" , $locales);

foreach($locales as $c => $l)
{
	if(strlen($l))
	{
		$parts = explode('.' , $l);
		$lc = $parts[0];
		
		list($lcode , $ccode) = explode('_' , $lc);
		
		$lcode = strtolower($lcode);
		
		$language = $language_codes[$lcode];
		$country = $country_codes[$ccode];
		
		if(strlen($language) and strlen($country))
		{
			$locale_data[$l] = "$language - $country - {$parts[1]}";
		}
	}
}

print_r($locale_data);

Now the above array can be used to generate a dropdown , from which the locale can be selected and saved.
