OK, I know this is stupid, but my diminished library cannot provide me an answer .
Using PHP conventions, there are two (2) ways to indicate inequality, !$var==[somevalue] and $var<>[somevalue].
I recall from my corporate days that there is a difference 'twixt the two (2), but cannot for the life of me recall it . In fact, those differences may not apply to PHP - I just cannot find an adequate reference , so I'm consulting my ultimate reference: DC .
There's a time to use $var<> and a time to use !$var==, but I simply cannot recall the rules and rationales .
I've been rebuilding a box for someone, and need to rebuild some PHP code as best I can - catastrophic failure combined with inadequate - dare I say inane? - backups has produced a need to rebuild some corrupted code segments. Trying to understand the logic of the original (?) coder is made more difficult by the use of these two (2) conventions.
