print time between 10pm to 3am - php

Question

I have 2 time strings as below:
10pm
3am
I want to print the time between above-given string like:
10pm
11pm
12am
1am
2am
3am
PHP Code I tried:
<?php
$new_otime = strtotime(date('H:i',strtotime('10pm')));
$close_time = strtotime(date('H:i',strtotime("3am")));
do { ?>
<option value="<?php echo date("g a",$new_otime) ?>"><?php echo date("g a",$new_otime); ?></option>
<?php
$new_otime = $new_otime+=3600;
} while ($new_otime == $close_time);
?>
But it echoes only 10 pm in the select box. How can I echo all the time between those string?

Answer 1

I suggest some work around to make this work:
<?php
$new_otime = strtotime(date('Y-m-d H:i',strtotime(date('Y-m-d').' 10pm')));
$close_time = strtotime(date('Y-m-d H:i',strtotime(date('Y-m-d').' 3am')));
if($close_time < $new_otime){
$close_time = strtotime(date('Y-m-d H:i',strtotime(date('Y-m-d',strtotime('+1 day')).'3am')));
}
do { ?>
<option value="<?php echo date("g a",$new_otime) ?>"><?php echo date("g a",$new_otime); ?></option>
<?php
$new_otime = $new_otime+=3600;
} while ($new_otime <= $close_time);
?>
Check if end time is bigger
If not make it next day
Loop while new_otime is less than close_time

Answer 2

You could also try using DateTime and DatePeriod:
$from = date_create_from_format('ha', '10pm');
//create 5 interations, each adds an additional hour
$dp = new DatePeriod($from, new DateInterval('PT1H'), 5);
/** #var DateTime $d */
foreach ($dp as $d) {
echo $d->format('ha');
}

I hope this is what you are looking for:
$time=22;
for($i=0;$i<6;$i++) {
echo date("g a",mktime($time+$i,0,0,09,21,2016))."<br>";
}

Answer 4

Try this
$new_otime = "10pm";
$close_time = "3am";
$counter=0;
while(date("g a",strtotime($new_otime)+3600*$counter)<=date("g a",strtotime($close_time))){
echo date("g a",strtotime($new_otime)+3600*$counter).'<br>';
$counter++;
}

Answer 5

Try this code
<?php
$new_otime = "10pm";
$close_time = "3am";
$new_otime = strtotime(date_create_from_format("ha", $new_otime)->format("ha"));
$close_time = strtotime(date_create_from_format("ha", $close_time)->format("ha"));
do {
?>
<option value="<?php echo date("ha", $new_otime) ?>"><?php echo date("ha", $new_otime); ?></option>
<?php
$new_otime = strtotime(date("ha", strtotime("+1 hours", $new_otime)));
} while ($new_otime != $close_time);
if ($new_otime == $close_time) {
?>
<option value="<?php echo date("ha", $new_otime) ?>"><?php echo date("ha", $new_otime); ?></option>
<?php } ?>
