在时区显示当前时间时出现问题

标签： php html

如果我添加

，有人可以解释为什么页面停止工作 
<?php
date_default_timezone_set("$tidszon");
echo "Klockan &auml;r " . date("h:i:sa")" i tidszonen du angav.";
?>

到代码的显示输入部分？其他一切正常，但如果我添加该页面甚至不加载..

这是未添加时区的默认代码：                           

<?php
// define variables and set to empty values
$y1 = $m1 = $d1= $y2 = $m2 = $d2=  $tidszon = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
   $y1 = test_input($_POST["y1"]);
   $m1 = test_input($_POST["m1"]);
   $d1 = test_input($_POST["d1"]);
   $y2 = test_input($_POST["y2"]);
   $m2 = test_input($_POST["m2"]);
   $d2 = test_input($_POST["d2"]);   
   $tidszon = test_input($_POST["tidszon"]);
}

function test_input($data) {
   $data = trim($data);
   $data = stripslashes($data);
   $data = htmlspecialchars($data);
   return $data;
}
?>

删除日期（“h：i：sa”）而不是使用

<?php
date_default_timezone_set("$tidszon");
echo "Klockan &auml;r " . date("h:i:sa")." i tidszonen du angav.";
?>

答案 1 :(得分：0)

.后发现date()：echo "Klockan &auml;r " . date("h:i:sa") . " i tidszonen du angav."

并在旁注。如果您可以使用例如utf-8编码而不是html实体，那么您和其他所有人都可以更轻松地阅读源代码。
