我想从MySQL数据库中选择数据并将其显示在一个目前为止工作的表中,但我对日期格式有疑问。
我想将MySQL Date重新格式化为dd / mm / YY,但我不知道该怎么做,因为我没有专门选择日期列。我只是从表中选择所有列。
代码:
<?php
echo "<table style='border: solid 1px black;'>";
echo "<tr><th>Id</th><th>Name</th><th>Date</th></tr>";
class TableRows extends RecursiveIteratorIterator {
function __construct($it) {
parent::__construct($it, self::LEAVES_ONLY);
}
function current() {
return "<td style='width: 150px; border: 1px solid black;'>" . parent::current(). "</td>";
}
function beginChildren() {
echo "<tr>";
}
function endChildren() {
echo "</tr>" . "\n";
}
}
$servername = "";
$username = "";
$password = "";
$dbname = "";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $conn->prepare("SELECT * FROM users");
$stmt->execute();
$result = $stmt->setFetchMode(PDO::FETCH_ASSOC);
foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
echo $v;
}
}
catch(PDOException $e) {
echo "Error: " . $e->getMessage();
}
$conn = null;
echo "</table>";
?>

是不是$ k是列名,$ v是值?
如果是,那么您可以轻松检测日期列值并对其进行格式化:
foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
switch ($k) {
case 'date_column':
// echo formatted $v
break;
default:
echo $v;
break;
}
}

以防我假设$k
为列而$v
为值是正确的,那么这应该有效:
foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
switch ($k) {
case '{{column_name}}':
// Format {{column_name}} as you like, e.g:
$date_time = strtotime($v);
print date("d-m-y", $date_time);
break;
default:
echo $v;
break;
}
}
