idate
(PHP 5)
idate — Format a local time/date as integer
Description
$format
[, int $timestamp = time()
] )
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.

The optional
timestampparameter is an integer Unix timestamp that defaults to the current local time if atimestampis not given. In other words, it defaults to the value of time().
Return Values
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.
Errors/Exceptions
Every call to a date/time function will generate a E_NOTICE
if the time zone is not valid, and/or a E_STRICT
or E_WARNING message
if using the system settings or the TZ environment
variable. See also date_default_timezone_set()

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>";
?>
