我想用mysql數據庫製作圖表。我有兩列 - 時間戳和溫度。這是時間戳格式 - 2015-06-11 22:45:59和溫度是整數。林不知道我的時間戳轉換爲JavaScript的時間是正確的,我有或可能我有其他錯誤。這是我的代碼:Highstock with php and mysql
data.php
<?
define('DBHOST','localhost');
define('DBUSER','root');
define('DBPASS','...');
define('DBNAME','diplomna2');
try {
//create PDO connection
$db = new PDO("mysql:host=".DBHOST.";port=3306;dbname=".DBNAME, DBUSER, DBPASS);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
//show error
echo '<p class="bg-danger">'.$e->getMessage().'</p>';
exit;
}
$stmt = $db->query('SELECT * FROM temperature');
$res=array();
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
$row['timestamp'] = strtotime($row['timestamp']);
$row['timestamp'] *=1000;
echo $res="[".$row['timestamp'] . ',' . $row['temperature'] ."]";
}
?>
這是輸出:
[1434051959000,25][1434051969000,26][1434051979000,26][1434051990000,28][1434052000000,27][1434052024000,25][1434052034000,24][1434052044000,23]

感謝您的快速響應。我改變了代碼,但它不再工作。 – Supreme
