将日期转换为其他格式？

我有被读出为20131212或20100125或者它可能是一个用户提交一个事件的任何日期的许多事件的日期（结构年月日）将日期转换为其他格式？

现在我已经做了一个功能，显示所有事件月。但日期被读出为20131212

我怎能取代20131212或任何日期，它是transfomed到 2013/12/12事件被存储在一个txt文件

的格式，这对于像所有结构这这可能吗？

一些代码wouldnt坏，我不知道你为什么得到的日期没有分离器......一般来说，哟你可以使用date_format来重新格式化日期。 –

加入一些代码。代码显示在一个txt文件中，并且读出 – Johan

你可以试试这个。它会为你工作。

<?php 
$str = '20131212'; 
$date = new DateTime($str); 
echo $date->format('Y/m/d'); 
?>

以上代码的输出是2013年12月12日

是的，但我现在不$ $ str将是20131212 ...它可以是任何日期。我想用dat格式来替换所有的8位数字 – Johan

man，只需要使用变量，而不是'$ str'，它将起作用... – Naryl

所以你可以设置$ str = $ _REQUEST ['date' ]。其中日期是任何用户输入日期的输入字段的名称。 –

你是指这个吗？

<?php 
$dt = '20131212'; 
$ctime = DateTime::createFromFormat('Ymd', $dt); 
echo $ndate= $ctime->format('Y/m/d'); // "prints" 2013/12/12

的确如此。我也应用了这些代码。但我不知道$ dt会是什么。它可能是20140416 ....那么是否有代码可以说$ dt是全部8位数字？ – Johan

如果你不知道它会是什么，你将不得不编写一些代码来找出：P –

但我已经尝试了很多，但我没有成功 – Johan

尝试这样

$yourdate= date('Ymd');  
echo date('Y-m-d',strtotime($yourdate));

我会给这个去编辑︰不工作今天的实际日期得到显示，但我的8位数字仍然像他们 – Johan

也许这样的事情会为你工作：

$new_dt=preg_replace('/^(\d{4})(\d{2})(\d{2})$/', "\1/\2/\3", $dt); 
if (strpos($new_dt, "/") === false) { 
    //did nothing since the date format was wrong! 
}else{ 
    echo "New date format: $new_dt"; 
}

你preg_replace尽我所能去，但我想成为现在:) thx所有，解决:) – Johan

，我发现我的问题的答案，希望别人发现这有帮助

<?php 
$file = fopen("admin/events/events.txt", "r"); 
while(!feof($file)){ 
    $line = fgets($file); 
$text= $line; 
$result=htmlentities($text); 
$s = $result; 
preg_match_all('/data-day=\'([^\']*)\'/', $s, $matches); 
foreach($matches[1] as $idx => $datevalue) 
{ 
    $year = substr($datevalue, 0, 4); 
    $month = substr($datevalue, 4, 2); 
    $day = substr($datevalue, 6, 2); 
} 
$line = str_replace("<div data-role='day' data-day='$year$month$day", "<b><u>Datum:</b></u> $year-$month-$day ", $line); 
$line = str_replace("'><div data-role='event' data-name='<h1>", " <br><b><u>Event:</b></u> ", $line); 
$line = str_replace("' data-start='", " <br><b><u>Start:</b></u> ", $line); 
$line = str_replace("' data-end='", " <br><b><u>Einde:</b></u> Tot ", $line); 
$line = str_replace("' data-location='", " <br><b><u>Locatie:</b></u> ", $line); 
$line = str_replace("</h1>", " <br><b><u>Inhoud event:</b></u><br> ", $line); 
$line = str_replace("'></div></div>", "", $line); 
echo "<div class='event'>$line</div>"; 
} 
fclose($file); 

?>
