This might help if you are trying to use multiple custom dictionaries especially if you don't have sudo access to the system aspell dictionary directory ...I created three custom dictionaries (or are they word lists) using "aspell create master" and found a way to use them ...1) Create 3 word lists, one word per line, wordlistA.txt, wordlistB.txt, and wordlistC.txt.2) Create 3 masters ... aspell --lang=en create master ./my_LANG-dictA.rws < wordlistA.txt - repeat for B and C (lang needs to be already installed, I think any lang will work).3) Create 3 multi files, my_LANGA.multi, contents: add my_LANG-dictA.rws) - repeat for B and C. Where my_LANGA can be any name in the same case as explained in the aspell manual.4) Use any one of them (A B or C) with pspell ...<?php$pspell_config = pspell_config_create('my_LANGC', '', ''. 'utf-8');pspell_config_dict_dir($pspell_config, <location of my_LANGC.multi>);if (($pspell = pspell_new_config($pspell_config)) == false) { echo 'pspell_new_config() for LANGC FAILED!');} else { $word = 'PHPisgreat']; if (pspell_check($pspell, $word)) { echo "$word: Valid spelling"; } else { $suggestions = pspell_suggest($pspell, $word); echo "$word: suggestions: $suggestions" }}?>The language arg for pspell_config_create() is the basename of the .multi file.Note that I do not have a file $HOME/.aspell.conf.Note that my .multi and .rws files are in the same directory, which I think is necessary.The wordlist files are not needed once the masters are created.
