First, you need to parse the string '06/22/2009' into a timestamp, possibly using strtotime():
首先，您需要将字符串 '06/22/2009' 解析为时间戳，可能使用strtotime()：
$dt = strtotime('06/22/2009');
Then, you can format the timestamp using date():
然后，您可以使用date()以下格式格式化时间戳：
$day = date("D", $dt);
If you especially want it in uppercase, use strtoupper():
如果您特别想要大写，请使用strtoupper()：
print strtoupper($day);
