HI!
I have a php page. There are music names (they are in array). I want to make a search script. This script must find what someone writes. But if user made mistake while writing, it must find similar music names. Is this possible, or I must use mysql?
Jump to PostHi!
You're trying to make something like Google Suggest.
Perhaps, you will use/need functions such as similar_text(), levenshtein(), soundex() and metaphone(). You can read about these functions ofc in official php-manual.
Good Luck!P.S.: Sorry for my bad English :)
Jump to PostThere are two functions in PHP that return the difference of two strings. The faster and probably better one is levenshtein:
levenshtein('ab', 'abc'); // 1 levenshtein('abc', 'a'); // 2 levenshtein('abc', 'ac'); // 1The other one is similar_text, that uses Oliver's description:
similar_text('ab', 'abc'); …

OK. What number would you put as maximal (diferences) (in levenshtein)?
I would make it (less than 2 or 3) or (less than 15% of the string you compare to).
Or: add all hits for $diff == 0 , and than (while you have less than 10 hits) add all hits for $diff == 1, 2, and 3.
OK. Thanks a lot!
