Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report

Description:
------------
I got a strange problem while comparing a numeric while with the string
"%". Using the numeric value 0 and the string "%" in an if-statement
results with true!?
Reproduce code:
---------------
$foo = '%';
$bar = 0;
if ($foo == $var)
{
echo "what the hell is going on?!\n";
}
$foo = '%';
$bar = '0';
if ($foo == $var)
{
echo "what the hell is going on?!\n";
}
