Fetching different templaets w/ same eval() statement???

[Antivirus]

I have the following 3 different eval statements based upon a conditional...

PHP Code:

foreach ($sc_gblockinfo AS $sc_gblock)
{
    if ($sc_gblock['pos'] == 'top')
    {
        eval('$sc_gblockbits_top .= "' . fetch_template('sc_gblock_edit_bit') . '";');
    }
    else if ($sc_gblock['pos'] == 'left')
    {
        eval('$sc_gblockbits_left .= "' . fetch_template('sc_gblock_edit_bit') . '";');
    }
    else if ($sc_gblock['pos'] == 'right')
    {
        eval('$sc_gblockbits_right .= "' . fetch_template('sc_gblock_edit_bit') . '";');
    }
} 


however i know it could be written more efficiently, and I have tried the following, along with different variations, however I just can't seem to figure it out...

PHP Code:

foreach ($sc_gblockinfo AS $sc_gblock)
{
    eval('$sc_gblockbits_' . $sc_gblock['pos'] . ' .= "' . fetch_template('sc_gblock_edit_bit') . '";');
} 


Within the loop, $sc_gblock['pos'] can be one of three possibilities, 'top', 'left', or 'right'... I'm basically just looking for a more compact way of writing the first example above.

Anyone got an idea of how to do this correctly?
