OK I have a very strange bug:
In the middle of my script I have these two lines:
var_dump($test,$test2);
echo "'$test'=='$test2' is ".($test==$test2);
which is giving:
int(0) string(6) "Points"
'0'=='Points' is 1
I understand that PHP is loose typed and automatically does type
conversion but in the many years I've been using PHP (mostly v4) the
comparison had always converted to 'string' and in the case above
returned FALSE, not TRUE. It seems here they are comparing as
integers thus 'Points' evaluates to 0 and the comparison is TRUE.
I tried comparing in the reverse sequence ($test2==$test) and the
same occurred. It does work as expected if I have === but the rest of
the scirpt isn't type sensitive so I want NULL, 0, and empty string
to still maintain equality.
Any ideas why this is suddenly happening? I'm using PHP 5.1, and I
realize I could use other functions such as strval() in the
comparison however I've used similar logic in the past without problems.
Any help would be great.
Thanks
Jeff
