get first day of week in php? 32 answers

im trying first day of given week based on inputting week number , year. im using current week , year , works charm.

$week = date('w'); $year = date('y'); $date1 = date('y-m-d', strtotime($year."w".$week.'1'));

however when seek input own week , year doesn't work

$week = 7; $year = 2013; $date1 = date('y-m-d', strtotime($year."w".$week.'1'));

what type if string should using strtotime? how come providing own date doesn't work?

because week numbers supposed padded (and 1 @ end doesn't anything):

$date1 = date( 'y-m-d', strtotime($year . 'w' . str_pad($week, 2, '0', str_pad_left)) );

php date datetime format
