The following script produces unexpected results:


$tmp = 0;
if ($tmp != "JBIJI") {
    echo "is true";
} else {
    echo "is false";


This produces "is false" as output where I would have thought that since the value of $tmp isn't "JBIJI" the expression "$tmp != 'JBIJI'" should evaluate true??

Apparently this is a 'usage/documentation' issue and not a PHP 'bug' per se. I'm happy for this to be closed now.
