hi,
$k="";
printf("\$k %s<br>",$k?"is set!":"is NOT set!");
printf("\$k=\"%s\" \$k %s<br>",$k, strcmp("0",$k)?"equals
ZERO!":"does
NOT equal ZERO!");
while ($k || "0"==$k) {
...
}
"while ($k || "0"==$k) {" is done in phplibs tree class which does not
work anymore with php4 and i guess that is because of line 3 of above
debug code gives $k equals ZERO!
