idate — Format a local time/date as integer
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.
| format character | Description |
|---|---|
| B | Swatch Beat/Internet Time |
| d | Day of the month |
| h | Hour (12 hour format) |
| H | Hour (24 hour format) |
| i | Minutes |
| I (uppercase i) | returns 1 if DST is activated, 0 otherwise |
| L (uppercase l) | returns 1 for leap year, 0 otherwise |
| m | Month number |
| s | Seconds |
| t | Days in current month |
| U | Seconds since the Unix Epoch - January 1 1970 00:00:00 UTC - this is the same as time() |
| w | Day of the week (0 on Sunday) |
| W | ISO-8601 week number of year, weeks starting on Monday |
| y | Year (1 or 2 digits - check note below) |
| Y | Year (4 digits) |
| z | Day of the year |
| Z | Timezone offset in seconds |
Der optionale Parameter timestamp ist ein Unix Timestamp als integer oder die aktuelle lokale Zeit wenn kein timestamp übergeben wurde. Er entspricht dann also dem Ergebnis der Funktion time().
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.
Jeder Aufruf der Datums- und Zeitfunktionen generiert eine E_NOTICE-Warnung, wenn die Zeitzone ungültig ist und eine E_STRICT-Nachricht oder eine E_WARNING-Warnung, wenn die Systemeinstellung oder die TZ-Umgebungsvariable genutzt wird. Siehe auch date_default_timezone_set()
| Version | Beschreibung |
|---|---|
| 5.1.0 | Erzeugt nun E_STRICT- und E_NOTICE-Zeitzonenfehler. |
Beispiel #1 idate() example
<?php
$timestamp = strtotime('1st January 2004'); //1072915200
// this prints the year in a two digit format
// however, as this would start with a "0", it
// only prints "4"
echo idate('y', $timestamp);
?>
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>";
?>
