Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. Previous Comments: ------------------------------------------------------------------------ [2002-11-11 05:14:29] [EMAIL PROTECTED] Derick I've recompiled with --disable-mb_string. The behaviour, doesnot change. I give you the ./configure directives from phpinfo() => './configure' '--prefix=/usr/local/apache' '--with-apxs=/usr/local/apache/bin/apxs' '--with-config-file-path=/usr/local/apache/php' '--with-dom=/usr' '--enable-socket=shared' '--with-ttf' '--enable-inline-optimization' '-enable-magic-quotes' '--enable-trans-id' '--enable-bc-math' '--enable-memory-limit' '--enable-wddx' '--enable-sysvshm=shared' '--with-iconv=/usr/local' '--with-png-dir=/usr' '--with-jpeg-dir=/usr' '--with-tiff-dir=/usr' '--with-freetype-dir=/usr' '--with-zlib-dir=/usr' '--with-gd=/usr' '--enable-gd-native-ttf' '--with-mysql=/usr/local/mysql' '--enable-ftp' '--with-pdflib=/usr/local' '--with-xpm-dir=/usr/X11R6' '--enable-xslt' '--with-xslt-sablot=/usr/local' '--with-expat-dir=/usr' '--with-mnogosearch=/usr/local' '--with-mcrypt=/usr/local' '--with-zlib=/usr' '--with-xmlrpc' '--enable-libgcc' '--with-java=/usr/java/j2sdk1.4.1' '--with-tsrm-pth' '--disable-mbstring' I solve the problem, on my side, through a dirty way (I check the presence of the varaible in the query string with an ereg :-( ). I think we must have the same behaviour...so it will be necessary to fix that. Feel free top ask me some other trials Marcel ------------------------------------------------------------------------ [2002-11-11 04:20:37] [EMAIL PROTECTED] Please recompile and add the configure option --disable-mbstring. Does the problem still occur then? Derick ------------------------------------------------------------------------ [2002-11-11 04:16:32] [EMAIL PROTECTED] 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($name)){ echo "it comes here if set even if the string is empty <BR>"; }else{ echo "it comes here NAME is not set <BR>"; } ?> With the previous http request : For 4.3.0-pre2 bibi is never set For 4.2.2 bibi is not set only when I remove = from the get URL, it seems logic Idea ? Thanks ------------------------------------------------------------------------ [2002-11-11 03:46:53] [EMAIL PROTECTED] I can't reproduce this, works fine for me: [derick@kossu derick]$ php <?php $foo = ""; if (isset($foo)) { echo "IN HERE!\n"; } ?> IN HERE!

Derick ------------------------------------------------------------------------ [2002-11-11 03:42:11] [EMAIL PROTECTED] On 4.2.2 I've if(isset($namevar)){ //some statements // It comes here if $namevar is set, even if $namevar=""; } On 4.3.0-pre2 I've if(isset($namevar)){ //some statements // It doesn't come if $namevar=""; } You can't change that to much legacy.... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=20353&edit=1
