This doesn't work since the value can be user defined and thus may span
multiple weeks :) The following works but is dirty, I'm sure there's a
better solution using modulus operator and adding and subtracting and a
little voodoo... I'm just too lazy atm to think it up ;)

<?php

$weekdays = array
(
'Mon' => true,
'Tue' => true,
'Wed' => true,
'Thu' => true,
'Fri' => true,
);

$daySeconds = (60 * 60 * 24);

$start = time();
$addWeekdays = 3;

$final = $start;
while( $i < $addWeekdays )
{
$final += $daySeconds;
echo date( 'D', $final )."\n";
if( isset( $weekdays[date( 'D', $final )] ) )
{
$i++;
}
}

echo 'Start: '.date( 'Y-m-d (D)', $start )."\n";
echo 'Final: '.date( 'Y-m-d (D)', $final )."\n";

Cheers,
Rob.
