[PHP-DEV] mysql-* versus db_* statements

[j . kuehne]

require_once "DB.php";                         
require_once "knowledge.inc";  
require_once "template-new.inc";  
         

function setupQuery($search_eb)
{
   // Show the wines stocked at the winestore that match
   // the search criteria
   
  $query = "SELECT *
             FROM knowledge_db
             WHERE MATCH (autor,problem) AGAINST ('$search_eb')
             OR id = ('$search_eb') 
             OR autor = ('$search_eb')  
             OR stichwort = ('$search_eb')
             OR date_new = ('$search_eb')
             OR anlage = ('$search_eb')";
             
   // Add region_name restriction if they've selected anything
  
  //$query .= "ORDER BY data_new";
   return ($query);
}

error_reporting(E_ALL);


// Show the user the knowledge that match their query
function showKnowledges($connection, &$template)
{
 

 // Produce a heading for the top of the page
 
 global $dsn;
 
   
 $template->setCurrentBlock();
 
 $template->setVariable("SUCH-KRITERIUM","Such-Kriterium: 
{$_SESSION["searchFormVars"]["search_eb"]}");  
 
 $browseString = "search_eb=" . 
urlencode($_SESSION["searchFormVars"]["search_eb"]);    
   
 $search = ($_SESSION["searchFormVars"]["search_eb"]);
 
 $link = mysql_connect("localhost", "root", "040573");
   
 $template->parseCurrentBlock();
 


mysql_select_db("knowledge", $link);

// Encode the search parameters for embedding in links to other pages 
// $connection = DB::connect($dsn, true);
$query = setupQuery($_SESSION["searchFormVars"]["search_eb"]);     
//$result = $connection->query($query);
//var_dump ($query);
[EMAIL PROTECTED]($query);
   
...


why I could not use the DB statement $result = $connection->query($query) 
instead of the mysql statement [EMAIL PROTECTED]($query); Further on, the same 
situation appears in the code, which looks like:


 for ( $rowCounter = 0;
            ($rowCounter < SEARCH_ROWS) &&
            (( $rowCounter + $_SESSION["searchFormVars"]["offset"]) <  
mysql_num_rows($result))  && 
            ($row =  mysql_fetch_array($result));
           //($row 
=mysql_fetch_row($_SESSION["searchFormVars"]["offset"]+$rowCounter));
           //   ($row = & $result->fetchRow(DB_FETCHMODE_ASSOC, 
$_SESSION["searchFormVars"]["offset"]+$rowCounter));
           $rowCounter++)


I could not use the DB statement ($row = & 
$result->fetchRow(DB_FETCHMODE_ASSOC, 
$_SESSION["searchFormVars"]["offset"]+$rowCounter)); 
instead of the mysql code ($row =  mysql_fetch_array($result)). But in that 
case, there is not the same meaning between the msyql and DB statement. 
However, I need the DB assignation for faultless work. What can I do?
