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;
}
?>
说明
array strptime
( string $date
, string $format
)
strptime() 返回一个将 date 解析后的数组，如果出错返回 FALSE。
月份和星期几的名字以及其它与语种有关的字符串对应于 setlocale()设定的当前区域（LC_TIME）。
参数
- date （string）
-
被解析的字符串（例如从 strftime() 返回的）
- format （string）
-
date 所使用的格式（例如同 strftime() 中所使用的相同）。
更多有关格式选项的信息见 strftime() 页面。
返回值
返回一个数组，失败则返回 FALSE。
| 键名 | 说明 |
|---|---|
| tm_sec | 当前分钟内的秒数（0-61） |
| tm_min | 当前小时内的分钟数（0-59） |
| tm_hour | 午夜起的小时数（0-23） |
| tm_mday | 月份中的第几天（1-31） |
| tm_mon | 自一月起过了几个月（0-11） |
| tm_year | 自 1900 年起过了几年 |
| tm_wday | 自星期天起过了几天（0-6） |
| tm_yday | 本年自一月一日起过了多少天（0-365） |
| unparsed | date 中未能通过指定的 format 识别的部分 |
范例
Example#1 strptime() 例子
<?php
$format = '%d/%m/%Y %H:%M:%S';
$strf = strftime($format);
echo "$strf\n";
print_r(strptime($strf, $format));
?>
上例的输出类似于：
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] => )

It's not the same as strptime. The array keys are different, for example '%d' will produce 'd' => '12'!!!
But it also returns false on failure.
<?php
function strToTime($date, $format) {
$search = array('%d', '%D', '%j', // day
'%m', '%M', '%n', // month
'%Y', '%y', // year
'%G', '%g', '%H', '%h', // hour
'%i', '%s');
$replace = array('(\d{2})', '(\w{3})', '(\d{1,2})', //day
'(\d{2})', '(\w{3})', '(\d{1,2})', // month
'(\d{4})', '(\d{2})', // year
'(\d{1,2})', '(\d{1,2})', '\d{2}', '\d{2}', // hour
'(\d{2})', '(\d{2})');
$pattern = str_replace($search, $replace, $format);
if(!preg_match("#$pattern#", $date, $matches)) {
return false;
}
$dp = $matches;
if(!preg_match_all('#%(\w)#', $format, $matches)) {
return false;
}
$id = $matches['1'];
if(count($dp) != count($id)+1) {
return false;
}
$ret = array();
for($i=0, $j=count($id); $i<$j; $i++) {
$ret[$id[$i]] = $dp[$i+1];
}
return $ret;
}
?>

fields of the returned struct referring to unspecified parts of the message are filled strangely:
print_r(strptime('19841203', '%Y%m%d'));
Array
(
[tm_sec] => 142611740
[tm_min] => 12
[tm_hour] => -1074490616
[tm_mday] => 3
[tm_mon] => 11
[tm_year] => 84
[tm_wday] => 1
[tm_yday] => 337
[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

//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
$informat = '%Y%m%d%H%M%S';
$outformat = '%A, %d %B %Y %T %Z';
$ftime = strptime("20060810084251",$informat);

1 ,
$ftime['tm_yday'] + 1,
$ftime['tm_year'] + 1900
);
//setlocale(LC_TIME,'pl_PL');
echo strftime($outformat , $unxTimestamp );

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().
