</WRAP>
===== Description =====
''$fnExecute'' provides a handle to a function that overrides the execute() function. The function should accept 3 parameters
  * An object containing the connection
  * The SQL statement
  * The bind variables

Execute returns the result of the override function.

===== Example =====
<code php>
function overrideExecute($db,$sql,$var)
{
    return 'Hello World';
}

$db->fnExecute = 'overrideExecute';

$sql = 'select * from customers';

$result = $db->execute($sql);

print $result;

/*
* prints 'Hello World'
*/
</code>
===== fnCacheExecute =====
The variable ''fnCacheExecute'' provides the same functionality as ''fnExecute'' but against the ''cacheExecute()'' method
