Question

我有一个如下工作的PHP代码，它使用来自mysql数据库的数据填充数组。它用于生成一个表，作为回报，在另一个php文件中使用它来生成谷歌图表。但我需要重新格式化“时间戳”中的数据。字段，使用函数JSdate（$ in，$ type）。作为一个菜鸟，当谈到PHP，我该怎么做？我想它应该在你遍历数据库中每条记录的部分完成，而不仅仅是写“时间戳”，它应该说是JSdate（＆＃39;时间戳＆＃39;，＆＃39; datetime＆＃39;），但我无法让它工作。对于有更多PHP经验的人来说可能是一个简单的问题; - ）

function JSdate($in,$type){
    if($type=='date'){
        //Dates are patterned 'yyyy-MM-dd'
        preg_match('/(\d{4})-(\d{2})-(\d{2})/', $in, $match);
    } elseif($type=='datetime'){
        //Datetimes are patterned 'yyyy-MM-dd hh:mm:ss'
        preg_match('/(\d{4})-(\d{2})-(\d{2})\s(\d{2}):(\d{2}):(\d{2})/', $in, $match);
    }

    $year = (int) $match[1];
    $month = (int) $match[2] - 1; // Month conversion between indexes
    $day = (int) $match[3];

    if ($type=='date'){
        return "Date($year, $month, $day)";
    } elseif ($type=='datetime'){
        $hours = (int) $match[4];
        $minutes = (int) $match[5];
        $seconds = (int) $match[6];
        return "Date($year, $month, $day, $hours, $minutes, $seconds)";   
    }
}


try {
    $dbname = 'database'; //  Add your Database name here
    $username = 'XXXXXX'; //  Add your Username here
    $password = 'XXXXXXX'; //  Add your password here
    $conn = new PDO("mysql:host=XXXXXXXXX;dbname=$dbname", $username,$password);
    echo "Connected successfully";
}catch(PDOException $e){
    echo "Connection failed: " . $e->getMessage();
}
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);


// First section of code is for generating data for Google Charts.
try {
  $result = $conn->query('SELECT *
  FROM tempdata_ny
  WHERE Timestamp > DATE_SUB(NOW(), INTERVAL 1000 HOUR)');


// Create the variables for the Google Chart and define as arrays   
  $rows = array();
  $table = array();

// Define the array labels
  $table['cols'] = array(
    array('label' => 'Datetime', 'type' => 'string'),
    array('label' => 'Temp1', 'type' => 'number'),
    array('label' => 'Temp2', 'type' => 'number')
  );
// Iterate through each record in the MySQL DB to populate the array        
 foreach($result as $r) {
      $data = array();
      $data[] = array('v' => (string) $r['Timestamp']);
      $data[] = array('v' => (float) $r['Temp_Sens1']);
      $data[] = array('v' => (float) $r['Temp_Sens2']);
    //  print "<pre>";
     // print_r($data);
    // print_r($r);
    //  print "</pre>";
      // Insert data array into $rows
      $rows[] = array('c' => $data);
    }


    $table['rows'] = $rows;


} catch(PDOException $e) {
    echo 'ERROR: ' . $e->getMessage();
}

更改

$data[] = array('v' => (string) $r['Timestamp']);

有关

$data[] = array('v' => (string) JSdate($r['Timestamp'],'datetime'));

填充PHP数组时调用函数
