# fnExecute & fnCacheExecute

##### Syntax

string $fnExecute
string $fnCacheExecute

## 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

    function overrideExecute($db,$sql,$var)
    {
        return 'Hello World';
    }

    $db->fnExecute = 'overrideExecute';

    $sql = 'select * from customers';

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

    print $result;

    /*
    * prints 'Hello World'
    */

## fnCacheExecute

The variable `fnCacheExecute` provides the same functionality as `fnExecute` but against the `cacheExecute()` method
