    (PHP 5, PHP 7, PHP 8)

    idate — Format a local time/date part as integer

    Descrizione

    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.

    Elenco dei parametri

    The following characters are recognized in the format parameter string
    format character Description
    B Swatch Beat/Internet Time

    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()

    y Year (1 or 2 digits - check note below)
    Y Year (4 digits)
    z Day of the year
    Z Timezone offset in seconds

    timestamp

    Il parametro opzionale timestamp è un integer timestamp Unix che ha come default l'ora locale attuale se un timestamp non è fornito. In altre parole, ha come default il valore di time().

    Valori restituiti

    Returns an int on success, o false in caso di fallimento.

    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.

    Errori/Eccezioni

    Ogni chiamata a una funzione data/ora genera un E_NOTICE se il time zone non è valido, e/o un messaggio E_STRICT o E_WARNING se si usano le impostazioni di sistema o la variabile d'ambiente TZ. Vedere anche date_default_timezone_set()

    Log delle modifiche

    Versione Descrizione
    8.2.0 Adds the N (ISO-8601 day of the week) and o (ISO-8601 year) format characters.

    Esempi

    Example #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>";
    ?>
