#18645 [NEW]: dot-operator allows bogus operations with shortcut for if

From: alpha@rrs.at Operating system: windows 2000 PHP version: 4.2.1 PHP Bug Type: Scripting Engine problem Bug description: dot-operator allows bogus operations with shortcut for if given this code <?php $var = 5; echo "string1 ".empty($var)?0:$var." string2"; // output "0" - WRONG echo "<br>"; echo "string1 ".(empty($var)?0:$var)." string2<br>"; // output "string1 5 string2" echo "<br>"; echo 'string1 '.empty($var)?0:$var.' string2'; // output "0" - WRONG echo '<br>'; echo 'string1 '.(empty($var)?0:$var).' string2<br>'; // output "string1 5 string2" echo '<br>'; ?> I get an error-message if I try echo 'string1 '.empty($var)?0.' string2'; or just echo 'string1 '.0.' string2'; , thus there is a missing error check at parse time. I don't know enough about the internal functions of PHP to say if it's the scripting engine or something else.
