HTML中的字符串在PHP中用json_encode無效

Question

我有一個數組，並且數組中的一個元素具有帶HTML標簽的字符串。 當我遍歷數組並回顯字段時，我可以看到字符串。

    $positions = $jobs_dbc->getData($sql);
    foreach($positions as $position) {
        echo $position['PositionDescription'];
    }

在下面的示例中，$ positions數組中總共有3個元素。 前兩個在PositionDescription中沒有HTML標記。 第三條記錄可以，並且我強調了上面代碼的結果：

但是-當我對數組進行json_encode時，該第三條記錄的PositionDescription顯示為NULL。

echo json_encode($positions, JSON_HEX_TAG|JSON_HEX_QUOT);

上面的代碼返回：

如何獲取HTML編碼的字符串？

更新：

var_export($positions)

Answer 1

我以為PositionDescription有HTML標記，但是一旦查看數據庫中的數據，我就會看到像項目符號這樣的字符，它們不是HTML標記，而是實際的符號。

json_encode必須為utf8字符。 將字段轉換為utf8后，json_encode開始返回字符串。

foreach($positions as &$position) {
        $position['PositionDescription'] = utf8_encode($position['PositionDescription']);
    }

echo json_encode($positions, JSON_HEX_TAG|JSON_HEX_QUOT);
