Obtener locales instalados en Azure Websites (PaaS)

Hola a todos, hoy les quiero compartir la solución a un problema con el que acabo de toparme. Algo fantástico de PaaS, y especialmente de Azure Websites es la abstracción que se le da al desarrollador sobre lo que sucede por “debajo” de la app. Por ejemplo, si yo soy un desarrollador PHP (o .NET, Java, Node.JS, HTML y JS, etc.) pongo mi foco en escribir el código y me olvido sobre la instalación de PHP (u otro). configuración del web server, instalación y mantenimiento del sistema operativo (SO) y así podemos seguir bajando hasta el hardware. Esto agiliza muchísimo los tiempos de desarrollo y reduce también los costos de administración y mantenimiento.

No obstante, existen escenarios donde necesitamos conocer un poco más sobre la capa subyacente a mi aplicación. Por ejemplo, que pasa si necesitamos conocer la lista de locales instalados en el sistema operativo?

Con estos simples pasos, les muestro una manera de consultar vía PHP la lista de locales instalados.

El código que tenemos que ejecutar será el siguiente:

<?php
header( 'Content-Type: text/html; charset=utf-8' );
// source of the list:
// https://msdn.microsoft.com/en-us/library/39cwe7zf(v=vs.90).aspx
$langs = array(
// language, sublanguage, codes

array( 'Norwegian', 'Norwegian (default)', array( 'norwegian' ) ),
array( 'Norwegian', 'Norwegian (Bokmal)', array( 'nor', 'norwegian-bokmal' ) ),
array( 'Norwegian', 'Norwegian (Nynorsk)', array( 'non', 'norwegian-nynorsk' ) ),
array( 'Polish', 'Polish', array( 'plk', 'polish' ) ),
array( 'Portuguese', 'Portuguese (default)', array( 'portuguese', 'ptg' ) ),
array( 'Portuguese', 'Portuguese (Brazil)', array( 'portuguese-brazilian', 'ptb' ) ),
array( 'Russian', 'Russian (default)', array( 'rus', 'russian' ) ),
array( 'Slovak', 'Slovak', array( 'sky', 'slovak' ) ),
array( 'Spanish', 'Spanish (default)', array( 'esp', 'spanish' ) ),
array( 'Spanish', 'Spanish (Mexico)', array( 'esm', 'spanish-mexican' ) ),
array( 'Spanish', 'Spanish (Modern)', array( 'esn', 'spanish-modern' ) ),
array( 'Swedish', 'Swedish', array( 'sve', 'swedish' ) ),
array( 'Turkish', 'Turkish', array( 'trk', 'turkish' ) )
);
echo '<table>'."\n";
echo '<tr>'."\n";
echo ' <th>Languange</th>'."\n";
echo ' <th>Sub-Languange</th>'."\n";
echo ' <th>Languange String</th>'."\n";
echo '</tr>'."\n";
foreach ( $langs as $lang ) {
echo '<tr>'."\n";
echo ' <td>'.$lang[0].'</td>'."\n";
echo ' <td>'.$lang[1].'</td>'."\n";
$a = array();
foreach ( $lang[2] as $lang_code ) {
$loc = setlocale( LC_ALL, $lang_code );
$a []= $lang_code.' '.( false === $loc ? '✖' : '✔ - '.$loc );
}
echo ' <td>'.implode( '<br>', $a ).'</td>'."\n";
echo '</tr>'."\n";
}
echo '</table>'."\n";
?>

Este script valida cuales son las locales instaladas, y en caso de estar instaladas, las imprime por pantalla.

Simplemente lo que hacemos es guardar este código en un archivo locale.php y lo subimos al web site. En mi caso, lo hice vía FTP. Luego finalmente ingreamos a nuestrositio.com/locale.php y veremos algo como lo siguiente:
