[英]PHP Check if date falls within certain hour
Given a DateTime Object how can I check if the hour falls under a certain range? 给定一个DateTime对象,如何检查小时是否在一定范围内?
$local_time = new DateTime();
//time is after 06:00:00 am
if (date('H', $local_time) >= 6) {
echo "After 6am";
}
DateTime objects are comparible: DateTime对象是可比较的:
$local_time = new DateTime();
$six_am = new DateTime('6am');
//time is after 06:00:00 am
if ($local_time > $six_am) {
echo "After 6am";
}
Note: this only works if the comparison is being done on the same day. 注意:仅在同一天进行比较时,此方法才有效。 It's gets more complex if you plan on crossing dates.
如果计划跨日期,它将变得更加复杂。
