$x = "";
if (isset($x))
print "X is set\n";
if (isset($y));
print "Y is set\n";
if (strlen($x) > 0)
print "X is set (SL)\n";
if (strlen($y) > 0)
print "Y is set (SL)\n";
###
The following script should at best print 'X is Set' because $x has
been set to "". However This is my output:
X is set
Y is set
$y is nowhere defined in the script, yet isset returns it as set.
Please feel free to contact if you need any more info.
