Hey

Is it possible to check a string of characters against a dictionary (to see if it's a real word)?
I have a script that basically gives me all the permutations of some characters, and I want my script to before it echo's it out to me, to check if it is a real word or not?

I figure I may have to connect to a SQL database.. but I don't want to upload a whole dictionary to my server... what's the best way to do this?
** NOTE:**
I now have a wordlist with a bunch of words... but how do I make it "check" it?

Depends on the format of your word list. Give us some more details and then we can assist more usefully.

Depending on how long your wordlist is, you could just parse the file into an array of words and then use in_array to check if your word is in it. This kind of linear search, however you might not want to do on a large list with a large number of requests. Adding the words to an SQL database might improve performance, but it will depend on the number of requests you're dealing with.

Assuming your words are line seperated:

PHP Code:

$path = '/path/to/file.txt';
$wordArray = file($path);

$myWord = 'someword';

if(in_array($myWord , $wordArray))
{
     //your word is in the dictionary
}
