PHP - Get a list of a particular day of the week between two dates

This is a modified version of function in the previous post. I had to modify it for a project I was doing.


****************************************************************************


function dayOfWeekListDateRange($start, $end, $day_of_week)
{
$range = array();

if (is_string($start) === true) $start = strtotime($start);
if (is_string($end) === true ) $end = strtotime($end);

if(!empty($day_of_week))
{
do
{
if(strcmp(strtolower(strftime("%A",$start)),strtolower($day_of_week)) == 0)
{
$range[] = date('Y-m-d', $start);
$start = strtotime("+ 1 day", $start);
}

else $start = strtotime("+ 1 day", $start);

}

while($start <= $end);
}

else
{

do
{

$range[] = date('Y-m-d', $start);
$start = strtotime("+ 1 day", $start);

}

while($start <= $end);
}

return $range;
}
