One more thing ... Bible is stored by verses, t is the text of the verse

I am working on a web based Bible searching query. So far I am able to
generate:
SELECT * FROM `bible_verses` INNER JOIN `bible_books` ON
`bible_books`.`id` = `bible_verses`.`b` WHERE `t` IN ( 'Lord' ,
'Jesus' ) LIMIT 0 , 10
Is an "IN" the correct syntax to use?
This will work fine. An "IN" clause is like multiple OR's:
... where t = 'Lord' OR t = 'Jesus' ...
I am trying to take what the user types in (variable is $keyword_search)
and allow a search where if the same 2 or 3 words are in the verse of
the Bible that verse would be a match, but not necessarily be beside
each other.
$keyword_search_string = str_replace(" ", "' , '", $keyword_search);
$query .= "IN ( '" . $keyword_search_string . "' ) ";
This will seem a little long winded but you need to check for sql
injection. As it stands, you'll get an error when you search for a name
with a quote (o'reilly). Might not be in the bible (I have no idea) but
doesn't mean someone won't try it ;)
// look at the keywords one by one - they are space separated
$keywords = explode(' ', $keyword_search);
// now go through them all and escape them.
$keyword_searches = array();
foreach ($keywords as $keyword) {
$keyword_searches[] = mysql_real_escape_string($keyword);
}
// then turn it all into an "IN" string.
$keyword_search_string = "IN ('" . implode("','", $keyword_searches) . "')";
You may want to eventually look at full text searching, depending on how
slow this is and how important search is to your site. The syntax is
completely different.
