This happens after enabling mbstring settings in php.ini ... mbstring is required by php-gettext package (see http://community.apachefriends.org/f/viewtopic.php?p=80970#80970). This doesn't happen in the server where I'm hosting my site.
Any ideas?

The default location of the php.ini file is xampp/apache/bin/php.ini

Also make sure your script is compatible with the version of php you are running on your server. Version 5 is not backward compatible so if you are running version 5 and your script is written for version 4 then you may have to change versions or make your script work with v5.

Check the version being used on your host's server and use the same version on your XAMPP server - phpinfo.php located in your webroot directory on both servers will give you a good comparison.
Good luck

Yes, I forgot to mention, the server uses PHP 4.4 and my box uses PHP 5. I've solved the problem replacing

Code: Select all

$this->accept_lang = $GLOBALS["HTTP_ACCEPT_LANGUAGE"] ;


with

Code: Select all

$this->accept_lang = getenv('HTTP_ACCEPT_LANGUAGE');


thanks izzy for your tip.

Thats the major flaw with php, it is not backward compatible and it should be. Not many scripting languages behave in this manner, thank goodness.

Really pleased for you that you have it all working now.
Best wishes Matias.

Notice: Undefined index: HTTP_ACCEPT_LANGUAGE in htdocs\mysite\classes\lang.class.php on line 18

Code: Select all

$this->accept_lang = $GLOBALS["HTTP_ACCEPT_LANGUAGE"] ; // <-- HERE

Then your client have not send the header "HTTP_ACCEPT_LANGUAGE" during this request.

BTW:
Instead of the $GLOBALS array, you may use the $_SERVER array:

Code: Select all

$this->accept_lang = $_SERVER["HTTP_ACCEPT_LANGUAGE"]; // <-- HERE

replacing with

Code: Select all

$this->accept_lang = getenv('HTTP_ACCEPT_LANGUAGE');

Now, if your browser don't send this header you have a (bool) "false" in "$accept_lang". and a (string) "" if the header is send with an empty string. (BTW: this is not working on IIS)

An other solution is a condition and test if this header is set/not empty. e.g.:

Code: Select all

if (empty($_SERVER["HTTP_ACCEPT_LANGUAGE"])) {
    $this->accept_lang = '';
} else {
    $this->accept_lang = $_SERVER["HTTP_ACCEPT_LANGUAGE"]; // <-- HERE
}

This happens after enabling mbstring settings in php.ini

There is no difference between with and without mbstring on by box when I test your class.
