使用php旋轉html表

Question

我有這個PHP代碼：

$query_production = "SELECT uploadedby as name, sum(points) as points,
date_format(uploaddate,'%Y-%m-%d') as date FROM imsexport 
WHERE uploaddate BETWEEN '2014-01-01 00:00:00' and '2014-01-20 23:59:59' 
GROUP BY uploadedby,date";
$result_production = mysql_query($query_production);
$row_production = mysql_fetch_assoc($result_production);

HTML表輸出為

  name        points      date
  John         147  2014-01-01
  Bob          79   2014-01-01
  Joe          156  2014-01-01
  Sue          116  2014-01-01
  John         117  2014-01-02
  Bob          186  2014-01-02
  Sue          74   2014-01-02
  Bob          233  2014-01-03
  John         159  2014-01-03
  Sue          162  2014-01-03
  Bob          162  2014-01-04
  Sue          38   2014-01-05

如何使用php旋轉此表使其看起來像這樣？ 我已經使用mysql完成此操作，但是代碼太長。

Name |2014-01-01|2014-01-02|2014-01-03|2014-01-04|2014-01-05
Bob      79          186       233         162      0
Joe      156          0         0           0       0
John     147         117       159          0       0
Sue      116          74       162          0       38

Answer 1

這將為您提供大部分幫助。 我剩下的是如何正確校正左偏移量（或date / points列對齊方式；提示，您需要將日期與名稱/點對保持一致，並知道它在$cols的偏移量）。

顯然，您正在處理數據庫中的行，因此會有所不同。

請參閱代碼下方的鍵盤演示鏈接。

<?php

$data = "John 147 2014-01-01
Bob 79 2014-01-01
Joe 156 2014-01-01
Sue 116 2014-01-01
John 117 2014-01-02
Bob 186 2014-01-02
Sue 74 2014-01-02
Bob 233 2014-01-03
John 159 2014-01-03
Sue 162 2014-01-03
Bob 162 2014-01-04
Sue 38 2014-01-05";

$data = explode("\n", $data);

$cols = array();
$pivot = array();

while ($line = array_shift($data)) {
    list($name, $points, $date) = explode(' ', trim($line));

    if (!$pivot[$name]) $pivot[$name] = array();

    array_push($cols, $date);

    array_push($pivot[$name], array('date' => $date, 'points' => $points));
}

$cols = array_unique($cols);

print_r($pivot);

echo implode('|', $cols);

echo PHP_EOL;

foreach ($pivot as $name => $row) {
    while ($entry = array_shift($row)) {
        echo str_pad($name, 7, ' ') . str_pad($entry['points'], 3, ' ', STR_PAD_LEFT) . '|';
    }

    echo PHP_EOL;
}

?>
