[2011-08-22 19:17:28] mads at gartneriet dot dk Maybe not a bug, but it is behaving different ind 5.3.7 than in the previous versions, which makes some of the code from PEAR that i use, give errors.

New Comment:
I have a question re. the correct behavior of custom __autoload() functions
when
called from is_a() in 5.3.7. How do we handle/report missing classes? is is_a()
prepared to handle any sort of exceptions or does it assume that __autoload
will
return TRUE/FALSE only?
what if I just did something like is_a("",ABCD)?

For reference:
The workaround is to do this
if (is_a($a, 'B')) {
becomes
if (is_object($a) && is_a($a, 'B')) {

This also affects HTML_Template_Flexy pear package that uses is_a to check
returned object against PEAR_Error class. No matter what behavior is right it
looks broken to me because I am patching this pear packages files right now!

@stas - the point of un-depreciating and working with a string was the second
argument, not the first one.
eg.
is_a($something, 'might_be_not_loaded_class')
rather than
$something instanceof might_be_not_loaded_class

Defiantly a bug..

DB_DataObject uses is_a() to check if a variable is both an object and an
instance of a particular object.
PEAR::isError() does too.
This just gives warnings in my code, and I could of course easily fix these two
places in my local pear-code. But then it will bite me the next time I upgrade
those packages from PEAR.
