gettext only translate to English in PHP - php

Question

I'm spanish, and making tests internacionalizing a text width PHP, i only get it translated to english.
I got this structure of files:
locale/en_US/LC_MESSAGES/con los ficheros messages.mo y messages.po
locale/es_ES/LC_MESSAGES/con los ficheros messages.mo y messages.po
locale/fr_FR/LC_MESSAGES/con los ficheros messages.mo y messages.po
Every files have the key word "Servicios" translated to each languaje.
And in PHP i have this code:
<?php
putenv("LANG=en_US");
setlocale(LC_ALL, "en_US");
bindtextdomain("messages", "locale");
textdomain("messages");
?>
When i put the code 'en_US' show the good translation, but when i change it to 'es_ES' or 'fr_FR' that way:
<?php
putenv("LANG=es_ES");
setlocale(LC_ALL, "es_ES");
?>
or
<?php
putenv("LANG=fr_FR");
setlocale(LC_ALL, "fr_FR");
?>
still showing the translation to English
I am working on Widnows 7 and the function
echo $_SERVER['HTTP_ACCEPT_LANGUAGE'] ;
returns to
"es-ES,es;q=0.8"
always,
Which problem could it be?
Thank you

It is quite likely that the languages are not installed on the server your running the script on - do you have shell access to the server? Then try
locale -a
to see which locales are installed. Also have a look here Is it feasible to rely on setlocale, and rely on locales being installed?
NOTE:
be careful with the LC_ALL setting, as it may introduce some unwanted conversions. For example, I used
setlocale (LC_ALL, "Dutch");
to get my weekdays in dutch on the page. From that moment on (as I found out many hours later) my floating point values from MYSQL where interpreted as integers because the Dutch locale wants a comma (,) instead of a point (.) before the decimals. I tried printf, number_format, floatval.... all to no avail. 1.50 was always printed as 1.00 :(
When I set my locale to :
setlocale (LC_TIME, "Dutch");
my weekdays are good now and my floating point values too.
