From: falk at brockerhoff dot org
Operating system: FreeBSD 5.3
PHP version:  4.3.10
PHP Bug Type: Unknown/Other Function
Bug description:  0 == '%' is true?

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;
}
