Re: FW: [Phplib-users] OOHForms and RegEx

[Andrew H. <ah...@ni...>]

its possible. php uses the regex libs from the host machine and 
sometimes quirky differences from host to host surface. usually ive only 
seen quirks in the case of malformed regex's like your [a-Z]. even if 
you had put them in the proper order [A-z] you would still be including 
some characters between Z and a that im sure were unintended (like the 
'\'). i couldnt even say why it would work at all in any environment.

hm, i just tested the egrep ranges from the command line of a linux box 
and a solaris box. the linux one seems to 'know what i mean.' the 
solaris one throws an error on [a-Z] but includes the intervening 
characters on [A-z] so there is indeed a compliance issue here.

a.g.h
