    Spelling suggestions for wrong spelling


    I came across this perl script someone wrote for spelling suggestions when someone types a wrong spelling. Can someone please convert it to PHP? It will help a lot of people.

    Source: http://www.norvig.com/spell-correct.html

    import re, collections
    def words(text): return re.findall('[a-z]+', text.lower()) 
    def train(features):
        model = collections.defaultdict(lambda: 1)
        for f in features:
            model[f] += 1
        return model
    NWORDS = train(words(file('big.txt').read()))
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    def edits1(word):
       s = [(word[:i], word[i:]) for i in range(len(word) + 1)]
       deletes    = [a + b[1:] for a, b in s if b]
       transposes = [a + b[1] + b[0] + b[2:] for a, b in s if len(b)>1]
       replaces   = [a + c + b[1:] for a, b in s for c in alphabet if b]
       inserts    = [a + c + b     for a, b in s for c in alphabet]
       return set(deletes + transposes + replaces + inserts)
    def known_edits2(word):
        return set(e2 for e1 in edits1(word) for e2 in edits1(e1) if e2 in NWORDS)
    def known(words): return set(w for w in words if w in NWORDS)
    def correct(word):
        candidates = known([word]) or known(edits1(word)) or known_edits2(word) or [word]
        return max(candidates, key=NWORDS.get)

    Just in case that looks like I am trying to get some kind-hearted people to do my work for me , no, it's just that I have no idea of Perl at all (even if I am okay at PHP), and do not have enough time to learn now . I thank anyone for any help.

    Have you thought of using a javascript on the clients machine to "Spell Check" before posting data? If you search the net for javascript spell checkers... you will find some on offer.
