idate

(PHP 5)

idateFormat 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.

Elenco dei parametri

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

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 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.

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()

$timestamp 
strtotime('1st January 2004'); //1072915200

// this prints the year in a two digit format

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>";
?>
