$user = 'glpi';
$users = array('glpi', 'glpi2', 'glpi3');
$users_groups = array('glpi', 'glpi2', 'glpi3');

$CFG_GLPI=array();

quotes / double quotes

{{{
echo 'dqmkdqmsl';
echo 'toto'.$test.' est vivant';
}}}

After reading bench about strings : http://www.estvideo.net/dew/index/page/phpbench
- Best choice seems to be simple quote.
ex : echo 'toto' not echo "toto"
- best is to concat vars and string.
ex : echo 'toto'.$test.' est vivant.'
- Best choice between echo and print is echo.

- Best choice to construct string before make echo, result : decrease number of use echo.
