You are right,but there is a change. I was not specific enough, in fact I send a variable through the get method http://somewhere/test_isset.php?bibi=&; The test_isset.php file is : <?php $namevar="bibi"; if(isset($$namevar)){ echo "it comes here even if the string is empty <BR>"; }else{ echo "it comes here NAMEVAR is not set or is empty <BR>"; } if(isset($name)){ echo "it comes here if set even if the string is empty <BR>"; }else{ echo "it comes here NAME is not set <BR>"; } ?> With the previous http request : For 4.3.0-pre2 bibi is never set For 4.2.2 bibi is not set only when I remove = from the get URL, it seems logic Idea ?
