Hello, I want to add the 'did you mean' feature (like on Google) on my shareware site, where a lot of users have mistypes, and they get 0 results... so they exit the site very fast. Do you have any idea how I could implement such a thing? Does it require a dictionary or something? I found some scripts, but none of them gave relevant results... just stupid, irrelevant suggestions. Any help would be appreciated... sample code would be awesome.
Thanks, Lucy

That's no easy task! Have you considered just putting a Google search form on your site though? I.e. a form that uses Google to search just within your site. It would be a lot easier!
The following functions will be of help to you. Look it up in your php manual
levenshtein()
soundex(),
similar_text(),
and metaphone().

I was actually wondering what else is there besides soundex() , thanks for the quick and dirty list! I might use this for a government app.

Thanks aktar!
OK, the winner is Yahoo Spelling Suggestion (which uses Yahoo API). This gives your site the possibility to suggest exactly what Yahoo Search suggests :cool: Awesome, I would say!
Here is a short summary about using it, if you guys want to use it too: it requires a Yahoo API key, which can be got free. It is limited to 5000 queries per day, so I suggest caching the suggestion (which I implemented, as my site has more then 5000 searches per day). The page returned by Yahoo needs to be parsed, and see if there is a suggestion given. This is a page that gives a suggestion, this is one that has no suggestion.
You can see it on my shareware site: link removed by moderator like "enail backup", "rgistry cleaner" or whatever you want. I also implemented a function to make bold italic the words that are different between the search query and the suggestion from Yahoo. ;)
If you need assistance on implementing this on your site, let me know.
Thanks, Lucy

Does it mean "(sizeof(int))* (p)" or "sizeof( (int)(*p) )" ?
According to my analysis, operator sizeof, (type) and * have the same
precedence, and they combine from right to left. Then this expression should
equal to "sizeof( (int)(*p) )", but the compiler does NOT think so. Why?
Can anyone help me? Thanks.
Best regards.

Hi,
I'm a terrible speller. So are many people, and I think it's getting
worse. That's why Googles' function to suggest re-searching with
corrected misspelled words is really nice.
Now I'm implementing an aspx page to handle 404 NotFound cases, and I
thought it'd be cool to look at the page name that the user tried to
access and see if it nearly matches any existing pages. Then I could
show a page like: "This file cannot be found. Did...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
