idate

(PHP 5, PHP 7, PHP 8)

idate — Format a local time/date as integer

Beschreibung

idate(string $format, ?int $timestamp = null): int|false

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.

Parameter-Liste

format

**The following characters are recognized in the `format` parameter string**
`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

timestamp

Der optionale Parameter timestamp ist ein Unix-Timestamp als int oder die aktuelle lokale Zeit, wenn timestamp nicht übergeben wurde oder null ist. Er entspricht dann also dem Ergebnis der Funktion time().

Rückgabewerte

Returns an int on success, Bei einem Fehler wird false zurückgegeben..

As idate() always returns an int and as they can't start with a "0", idate() may return fewer digits than you would expect. See the example below.

Fehler/Exceptions

Jeder Aufruf der Datums- und Zeitfunktionen generiert einen Fehler der Stufe E_WARNING, wenn die Zeitzone ungültig ist. Siehe auch date_default_timezone_set()

Changelog

Version	Beschreibung
8.0.0	`timestamp` is nullable now.

Beispiele

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>";
?>
