PHPを使用してJSONをHTMLテーブルに解析するにはどうすればよいですか？
私のウェブサイトでテーブルを取得する必要があります。そして、このテーブルのデータを " http://west.basketball.nl/db/json/stand.pl?szn_Naam=2014-2015&cmp_ID=37 "から取得する必要があります。ものの何もうまくいきません....
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript"
src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
</head>
<body>
<?php
$json=file_get_contents("http://west.basketball.nl/db/json
/stand.pl?szn_Naam=2014-2015&cmp_ID=373");
$data = json_decode($json);
if (count($data)) {
// Open the table
echo "<table>";
// Cycle through the array
foreach ($data as $stand) {
// Output a row
echo "<tr>";
echo "<td>$afko</td>";
echo "<td>$positie</td>";
echo "</tr>";
}
// Close the table
echo "</table>";
}
?>
</body>
</html>
外部ソースからデータを取得するときに最初に行うことは、何が返されるかを理解することです。
そうする
<?php
$json=file_get_contents("http://west.basketball.nl/db/json/stand.pl?szn_Naam=2014-2015&cmp_ID=373");
$data = json_decode($json);
print_r($data);
結果：

これで、スカラー値や配列ではなく、OBJECTを扱っていることがわかりました。
だからこのコードを試してください：
<?php
$json=file_get_contents("http://west.basketball.nl/db/json/stand.pl?szn_Naam=2014-2015&cmp_ID=373");
$data = json_decode($json);
if (count($data->stand)) {
// Open the table
echo "<table>";
// Cycle through the array
foreach ($data->stand as $idx => $stand) {
// Output a row
echo "<tr>";
echo "<td>$stand->afko</td>";
echo "<td>$stand->positie</td>";
echo "</tr>";
}
// Close the table
echo "</table>";
}
?>
再帰的な方法が必要な場合：
_public static function jsonToDebug($jsonText = '')
{
$arr = json_decode($jsonText, true);
$html = "";
if ($arr && is_array($arr)) {
$html .= self::_arrayToHtmlTableRecursive($arr);
}
return $html;
}
private static function _arrayToHtmlTableRecursive($arr) {
$str = "<table><tbody>";
foreach ($arr as $key => $val) {
$str .= "<tr>";
$str .= "<td>$key</td>";
$str .= "<td>";
if (is_array($val)) {
if (!empty($val)) {
$str .= self::_arrayToHtmlTableRecursive($val);
}
} else {
$str .= "<strong>$val</strong>";
}
$str .= "</td></tr>";
}
$str .= "</tbody></table>";
return $str;
}
_次にecho YourClass::jsonToDebug($jsonText)を呼び出します。
試してみませんか？
$data = json_decode($json, true);
おそらく、問題はあなたが使用している変数にあります-$afkoおよび$positie。以下のコードでお試しください-
// Cycle through the array
foreach ($data as $stand) {
// Output a row
echo "<tr>";
echo "<td> . $stand['afko'] . </td>";
echo "<td> . $stand['positie'] . </td>";
echo "</tr>";
}
