Check time in range php
|
I have to check if the current daytime falls in a specific range. I looked up the internet and found several similar solutions like this one: If both conditions have to be true, how can this bis achieved when we assume that $start is 06:00:00 and $end is 02:00:00. If we make the assumption that it is 01:00:00, in this case the first condition can't be true. Has anybody an idea to handle this problem differently? Thanks! asked Nov 17, 2014 at 17:37
2 Naturally, you'd have to account for date in your comparisons. answered Nov 17, 2014 at 17:54

PHP check if time falls within range, questioning common solution$now = date("His");//or date("H:i:s")
$start = '130000';//or '13:00:00'
$end = '170000';//or '17:00:00'
if($now >= $start && $now <= $end){
echo "Time in between";
}
else{
echo "Time outside constraints";
}
= $start && time() <= $end) {
// ok
} else {
// not ok
}
function isWithinTimeRange($start, $end){
$now = date("His");
// time frame rolls over midnight
if($start > $end) {
// if current time is past start time or before end time
if($now >= $start || $now < $end){
return true;
}
}
// else time frame is within same day check if we are between start and end
else if ($now >= $start && $now <= $end) {
return true;
}
return false;
}
echo isWithinTimeRange(130000, 170000); date_default_timezone_set("Asia/Colombo");
$nowDate = date("Y-m-d h:i:sa");
//echo ' // if current time is past start time or before end time
if($now >= $start || $now < $end){
// if current time is past start time or before end time
if($now >= $start || $now <= $end){
