Summary: 0003309: simplexml array elements always test as true
Description: <?php
print "
";

$xml = '<?xml version="1.0" encoding="UTF-8"?><foo><bar>123</bar><bat/></foo>';

$sxml = simplexml_load_string($xml);



if ($sxml->bar) print "bar is set in obj\n";

if ($sxml['bar']) print "bar is set in array\n";

if ($sxml['xyz']) print "xyz is set in array\n";



Regular PHP prints "bar is set in obj". Quercus prints that plus the two array lines.



It surprises me that the second "if" doesn't test true in regular PHP, but the third one definitely shouldn't.

Sorry, my test program was not so great. Here's a better version:

<?php
$xml = '<?xml version="1.0" encoding="UTF-8"?><foo xyz="1"><bar>123</bar><bat/></foo>';
$sxml = simplexml_load_string($xml);

if ($sxml->bar) print "bar is set in obj\n";
if ($sxml->xyz) print "xyz is set in obj\n";
if ($sxml['bar']) print "bar is set in array\n";
if ($sxml['xyz']) print "xyz is set in array\n";

Regular PHP prints

bar is set in obj
xyz is set in array

Quercus prints

bar is set in obj
bar is set in array
xyz is set in array
