我尝试过的最令人沮丧的事情-就是这里！
<?php function getWeeks($date, $rollover) { $cut = substr($date, 0, 8); $daylen = 86400; $timestamp = strtotime($date); $first = strtotime($cut . "00"); $elapsed = ($timestamp - $first) / $daylen; $weeks = 1; for ($i = 1; $i <= $elapsed; $i++) { $dayfind = $cut . (strlen($i) < 2 ? '0' . $i : $i); $daytimestamp = strtotime($dayfind); $day = strtolower(date("l", $daytimestamp)); if($day == strtolower($rollover)) $weeks ++; } return $weeks; } // echo getWeeks("2011-06-11", "sunday"); //outputs 2, for the second week of the month?>
