idateFormat a local time/date as integer


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.



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


O parâmetro opcional timestamp é um integer Unix timestamp cujo padrão é a hora local se timestamp não for dado. Em outras palavras, o padrão é o valor de time().

Valor Retornado

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.


Toda a chamada a uma função de data/hora irá gerar um se a zona da hora não for valida, e/ou uma mensagem E_STRICT ou E_WARNING se estiver usando a definição do sistema ou a variável de ambiente TZ. Veja também date_default_timezone_set()


Versão Descrição

Agora lançam erros E_STRICT e E_NOTICE .


Exemplo #1 idate() example

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:

function hour ( $a, $b )
$timestamp = strtotime(''.$a.':'.$b.':00');
$aa = idate('H', $timestamp);
$bb = idate('i', $timestamp);
$bb=="0") { $cc = "00"; } else { $cc = $bb; }
$dd = $aa.".".$cc;

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.

echo "<select name=\"example\">";
$iii = $ii * 15;
$hour = hour($i, $iii);
"<option value=\"".$hour."\">".$hour."</option>";
