Hi:

Someone using PEAR DB just filed a bug report.  It turns out PHP's 
behavior has changed when trying to find a "property" of a string:

    php -r "$str = 'Hello'; var_dump(isset($str->prop));"

In 5.0.0, 5.0.1 and 5.0.2 it returns false.  But in 5.0.3 it returns true.

In a PHP 4 snapshot from today, it still returns false, as it always has.

This behavior changed in HEAD some time between 2004-10-31 and 2004-12-16.

Those on *nix like systems would probably rather use this:

      php -r '$str = "Hello"; var_dump(isset($str->prop));'

Uh, ignore that statement.  Now that I think about it, my test used PHP 5, 
not 4.  (PATH intercepted the command despite being in the php4 
directory.)  I'll test PHP 4 later.

We found the bug. Do you think this warrants a 5.0.4?
