strftime
For Windows user! It's rather the same as strptime!
It uses the previous function: but call strToTime($date, $format) to strToDate($date, $format) because this name is forgiven!
<?php
function strToDateTime($date, $format) {
if(!($date = strToDate($date, $format))) return;
$dateTime = array('sec' => 0, 'min' => 0, 'hour' => 0, 'day' => 0, 'mon' => 0, 'year' => 0, 'timestamp' => 0);
foreach($date as $key => $val) {
switch($key) {
case 'd':
case 'j': $dateTime['day'] = intval($val); break;
case 'D': $dateTime['day'] = intval(date('j', $val)); break;
case 'm':
case 'n': $dateTime['mon'] = intval($val); break;
case 'M': $dateTime['mon'] = intval(date('n', $val)); break;
case 'Y': $dateTime['year'] = intval($val); break;
case 'y': $dateTime['year'] = intval($val)+2000; break;
case 'G':
case 'g':
case 'H':
case 'h': $dateTime['hour'] = intval($val); break;
case 'i': $dateTime['min'] = intval($val); break;
case 's': $dateTime['sec'] = intval($val); break;
}
}
$dateTime['timestamp'] = mktime($dateTime['hour'], $dateTime['min'], $dateTime['sec'], $dateTime['mon'], $dateTime['day'], $dateTime['year']);
return $dateTime;
}
?>
Descripción
array strptime
( string $marca_de_tiempo
, string $formato
)
strptime() devuelve una matriz que contiene el valor marca_de_tiempo manipulado según el formato o FALSE si se ha producido un error.
Los nombres de los meses y de los días de la semana y otras cadenas dependientes del idioma, siguen la configuración de localización actual, establecida con setlocale() (LC_TIME).
Lista de parámetros
- marca_de_tiempo (string)
-
Una marca de tiempo (igual que la devuelta por strftime())
- formato (string)
-
El formato usado en formato (igual que el usado en strftime()).
Para más información sobre las opciones del formato, puede consultar la página de la función strftime().
Valores retornados
Devuelve una matriz o FALSE si se produce un error.
| Parámetros | Descripción |
|---|---|
| tm_sec | Segundos transcurridos del minuto actual (0-61) |
| tm_min | Minutos transcurridos de la hora actual (0-59) |
| tm_hour | Horas transcurridas desde la media noche (0-23) |
| tm_mday | Día del mes (1-31) |
| tm_mon | Meses transcurridos desde Enero (0-11) |
| tm_year | Años transcurridos desde 1900 |
| tm_wday | Días transcurridos desde el Domingo (0-6) |
| tm_yday | Días transcurridos desde el 1 de Enero (0-365) |
| unparsed | La parte de la marca_de_tiempo que no se pudo reconocer empleando el parámetro formato |
Ejemplos
Example #1 Ejemplo de strptime()
<?php
$formato = '%d/%m/%Y %H:%M:%S';
$fecha_formateada = strftime($formato);
echo "$fecha_formateada\n";
print_r(strptime($fecha_formateada, $formato));
?>
El resultado del ejemplo seria algo similar a:
03/10/2004 15:54:19 Array ( [tm_sec] => 19 [tm_min] => 54 [tm_hour] => 15 [tm_mday] => 3 [tm_mon] => 9 [tm_year] => 104 [tm_wday] => 0 [tm_yday] => 276 [unparsed] => )

If strptime() fails to match all of the format string and therefore an error occurred the function returns NULL.

The result of strptime() is not affected by the current timezone setting, even though strftime() is. Tested in PHP 5.1.6.

If you need strptime but are restricted to a php version which does not support it (windows or before PHP 5), note that MySQL since Version 4.1.1 offers (almost?) the same functionality with the STR_TO_DATE function.
See http://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html

<?php
//This turns non-standard but often used "datetime" string
//like '20060810084251' into nice formatted date
//'Thursday, 10 August 2006 08:42:51 CEST'
//note, that strptime returns day of year counting from 0, so
//you need to put 1 as month number to get appropriate
//month for the daycount. for 2006 strptime for unknown
//reason returns 106, so I simply add 1900

It says "Parse a time/date generated with strftime()" but that's not entirely correct -- While strptime("2006131", "%Y%W%u") works as expected, strptime("2006131", "%G%V%u") returns false instead of reversing the equivalent - and unambiguous - strftime() usage. I suspect that's because glibc doesn't support that. Anyway, this docu page fails to mention that apparently not all format components supported by strftime() can be used with strptime().
