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>";
?>
idate
(PHP 5)
idate — Format a local time/date as integer
Descrizione
int idate
( string
$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.
