复制代码 代码如下:
// 格式化日期
static function formatDate($format, $datetime, $week = 0) {
$datetime = $datetime > 3000 ? $datetime : strtotime($datetime);
if ($week) {
$weeknames = [
'日',
'一',
'二',
'三',
'四',
'五',
'六'
];
$format = str_replace('w', $weeknames [date('w', $datetime)], $format);
}
return date($format, $datetime);
}

复制代码 代码如下:
echo "周" . formatDate("w","2012-11-03 00:46:22" , 1) . " " . formatDate("Y-m-d", "2012-11-03 00:46:22");
echo "周" . formatDate("w","1388678400" , 1) . " " . formatDate("Y-m-d", "1388678400");
