Enchant is the PHP binding for the
» Enchant library. Enchant steps
in to provide uniformity and conformity on top of all spelling
libraries, and implement certain features that may be lacking in
any individual provider library. Everything should "just work"
for any and every definition of "just working."
Enchat supports the following backends:
Aspell/Pspell (intends to replace Ispell)
Ispell (old as sin, could be interpreted as a defacto standard)
MySpell/Hunspell (an OOo projects, also used by Mozilla)
Uspell (primarily Yiddish, Hebrew, and Eastern European languages - hosted in AbiWord's CVS under the module "uspell")
AppleSpell (Mac OSX)
