Ajdin, you may want to take a look at mnoGoSearch, which is search engine
software with a C indexer, PHP front-end and ability to work with numerous
databases, including MySQL.  It's a great program, but even if it's not
suitable for what you're doing I suggest looking at the PHP code and
database structure.  mnoGoSearch has incorporated the ability to search for
related words by incorporating a dictionary file and a database table of
grammar rules so a search for one word can be made to find other forms of
that word.

FYI, to break a string into an array like you describe use strlen() to get
the length of the string, substr() to pull out the first N characters from
the string, then loop through and add each element to an array by adding as
follows (pseudocode):

for ( $i = strlen( $string ); $i >= 0; $i-- )
$array[] = substr( $string, 0, $i );
