Toby Bartels (talk | contribs) More on the PHP "feature" near brackets. |

Line 14:
:There's a fun "feature" in PHP whereby the string "0" is sometimes considered to be equal to the empty string "" because, as far as I can tell, a numerical comparison is being used. This sounds suspiciously like an instance of that problem; I'll look into it... [[user:Brion VIBBER|Brion VIBBER]], Wednesday, April 17, 2002
Here's another bug that I suspect is related. A less than symbol ("<") that's the beginning of an HTML tag will sometimes be displayed in the diff as "&lt;" instead of "<". This again occurs after a bracketing delimiter. As for >, an analogous effect occurs ''before'' a bracketing delimiter. For an example of this, see the diff for my edit today of [[ring ideal]]. -- [[user:Toby Bartels|Toby Bartels]] again (2002/05/05)
PS: I did a little experimenting -- see the history of [[user:Toby/sandbox]] -- and found it amazingly difficult to reproduce the effect. I could reproduce it with "0" only when the "0" was in red, and couldn't manage to reproduce it with "<" and ">" at all under a general condition. Take a look, if this might help.
