Description:
------------
In my .po file, there is :

msgid "Hello"
msgstr "Bonjur"

gettext() return : Bonjur

If I update my .po file with :

msgid "Hello"
msgstr "Bonjour"

and generate a new .mo file, gettext() return again : Bonjur

Apache must be restarted to gettext() return : Bonjour

Reproduce code:
---------------
<?php

putenv('LANG=myLocale');
setlocale(LC_ALL, 'myLocale');
bindtextdomain('mydomain', 'path_to_locale_directory');
textdomain('mydomain');

echo gettext('Hello');

?>


Expected result:
----------------
If .mo file is updated, gettext() must return updated value.
