A function that made by idate for print a hour you want:
<?php
function hour ( $a, $b )
{
$timestamp = strtotime(''.$a.':'.$b.':00');
$aa = idate('H', $timestamp);
$bb = idate('i', $timestamp);
if($bb=="0") { $cc = "00"; } else { $cc = $bb; }
$dd = $aa.".".$cc;
return($dd);
}
?>
Why should i use it?
For example:
You have to print 08:00 to 21:00 by 15 minutes periods.
This is a useful code for shipping sites for delivery time.
<?php
echo "<select name=\"example\">";
for($i=8;$i<=20;$i++)
{
for($ii=0;$ii<=3;$ii++)
{
$iii = $ii * 15;
$hour = hour($i, $iii);
echo "<option value=\"".$hour."\">".$hour."</option>";
}
}
echo "</select>";
?>

(PHP 5, PHP 7)
idate — Format a local time/date as integer
Beschreibung
idate
( string
$format
[, int $timestamp = time()
] ) : int
Returns a number formatted according to the given format string using the
given integer timestamp or the current local time
if no timestamp is given. In other words, timestamp
is optional and defaults to the value of time().
Unlike the function date(), idate()
accepts just one char in the format parameter.

Der optionale Parameter
timestampist ein Unix Timestamp als integer oder die aktuelle lokale Zeit wenn keintimestampübergeben wurde. Er entspricht dann also dem Ergebnis der Funktion time().
Rückgabewerte
Returns an integer.
As idate() always returns an integer and as they can't start with a "0", idate() may return fewer digits than you would expect. See the example below.
