Old Summary: comparing 0=="null" is true?
Status: Open
Bug Type: Scripting Engine problem
Operating System: Win2k
PHP Version: 4.0.6
New Comment:

i thought that any integer =0 was also equal to any string...

for example (in your script):

$MyVar=0;
if ($MyVar=="blahblahblahblah")
echo "yes";
else
echo "no";


will echo "yes"

I don't know if this is supposed to happen, but it does.
If you set the $MyVar=1, the script prints no.

Can anybody else verify if this is supposed to happen, or
if this is actually a bug?

If you compare the integer(0) to the string "null", PHP thinks they are the same.

Am I hopped up on goofballs, or whats up here?

$MyVar=0;
if($MyVar=="null")
	print("apparently $MyVar is equal to \"null\"");
else
	print("its not null, its $MyValue");
