SQL INJECTION
 A database query syntax error has occurred. This could be because of an illegal search query (see Searching PhpCOIN 
Docs), or it may indicate a bug in the software. The last attempted database query was:

    SELECT cur_id,cur_namespace,cur_title,cur_text FROM cur,searchindex WHERE cur_id=si_page AND ( ( (MATCH (si_title) 
AGAINST ('SQL_INJECTION')) ) AND cur_namespace IN (0,9,11) LIMIT 0, 20

from within function "SearchEngine::showResults". MySQL returned error "1064: You have an error in your SQL syntax near 
'LIMIT 0, 20' at line 1".

Possible Fixes: The usage of htmlspeacialchars(), mysql_escape_string(), mysql_real_escape_string() and other functions 
for input validation before passing user input to the mysql database, or before echoing data on the screen, would solve 
these problems.
