Spell Checker

Spell Checker is a class meant to check the spelling of text using only basic PHP commands, thus not using any special purpose extensions. It uses a dictionary text file as its spelling knowledge base. For greater performance, the class uses the dictionary words (currently almost 40,000) to build a dynamic hashed lookup table. The class can also provide suggestions for the misspelled words that are found. The dictionary file can be updated to include any missing words.
