curious... when I ran through that (before posting initially) was getting the
following from print_r of the file() results...
Array
(
[0] => admin
[1] => user1
[2] => user2
[3] => user3
[4] =>
)
which lead me to believe that the last \n was parsing as an extra element in the
array... (not sure why), thus the dilema of either trimming each element of the
array, or pop'ing an element off the end of the array. both seemed annoying,
thus the post
after recoding it with each/trim into new array and use that for checking
validity... I redid the original file using the script and got different
results;
Array
(
[0] => admin
[1] => user1
[2] => user2
[3] => user3
)
which is what I expected in the first place... as such, the original code could
now just check for the username with a ."\n" on the end (as you recommended).
Futsed up there somewhere... thus the seemingly stupid question.
cheers,
Dave
