HTML日期不输出与输入相同？

标签： php html date

我在这里有一个小问题，我的输入日期显示为dd / mm / yyyy然而当我使用我的php获取此数据并做一个简单的回声来检查一切正常时，它会输出yyyy / mm / dd（向后）任何想法为什么会这样？

示例

输入：

日/月/年

2016年1月2日

输出：

YYYY / MM / DD

2016年2月1日

HTML

＆＃13;
＆＃13; 
<form method="post" action="MyDoc.php" autocomplete="off">
  <input type="date" name="date_1A5">
</form>
＆＃13;
＆＃13;
＆＃13;

PHP 

<?php
  if ($_SERVER['REQUEST_METHOD'] == 'POST'){
      $risk_1A5 = $_POST['date_1A5'];
      echo 'Risk_1A5: '.$risk_1A5.'<br>';
  }
?>

答案 0 :(得分：1)

您可以执行以下操作，我在评论中对其进行了解释，您可以在以下代码中根据需要重新格式化日期，格式可能会有所不同，但可以根据需要更改输入格式和输出格式。

if (isset($_POST['date'])) {

    // Get the date
    $input = $_POST['date'];

    // Create a DateTime object from the input
    $date = DateTime::createFromFormat('Y-m-d', $input);

    // Format it to your needs
    $formatted = $date->format('d-m-Y');

    // Echo it out
    echo $formatted 
}

答案 1 :(得分：1)

这是因为您正在使用type="date"（https://www.w3.org/TR/html-markup/input.date.html），它应该以[{1}}格式返回日期（请将其读作yyyy-mm-dd）。
你可以用另一种格式输入它，我认为它与浏览器语言环境有关，但它会以输出它的格式保存值。

您无法更改此行为（Is there any way to change input type="date" format?）。

如果你想以另一种格式显示它，你可以使用像

这样的东西在php端进行详细说明。 
Y-m-d

然后，您可以使用$output_date = date_parse_from_format("Y-m-d", $input_date); 显示正常的PHP date()。

更新

对不起，我的错字。 date('d/m/Y', $output_date)为您提供了一个分割日期的数组。

更简单的解决方案：

用

解析它 
date_parse_from_format()

然后将其重新转换为带有

的字符串 
$output_date = date_create_from_format("Y-m-d", $risk_1A5);

示例输入 

date_format($output_date, 'd/m/Y');

输出 

print_r($date = date_create_from_format("Y-m-d", "2016-12-21"));

var_dump(date_format($date, 'Y-m-d'));

答案 2 :(得分：0)

这不是错误，日期的表示与它的值不同。

应用程序（浏览器）可以根据国家/操作系统/系统配置等以适当的方式呈现值。

这意味着用户可以看到他/她可能常见的格式的值。该格式可能与PHP转储的输出不同，后者在服务器上格式化。
