從文件中檢索數據並生成動態表

Question

我有一個文件File3：

[File3] 
Time | Name | Name | ID1 | ID2 
15:50 | Alex | Web | * 38 | 5 
10:50 | Xyz | Xxx | * 55 | 65 
10:50 | Volume | Xxx | 55 | 65 
12:50 | Kate | Uh | 35 | 62 
15:50 | Maria | Zzz | 38 | 67 

生成文件，時間只能有一行，下一次可能是30

我不太擅長使用PHP編寫代碼，而是想編寫一個腳本來下載文件並將其加載到動態表中的PHP行中，該行帶有以[*]標記的徽標，整個行應為紅色。

結果：

====================================
| Time | Name |Surname| ID1  | ID2 |
====================================
|15:50 | Alex |  Web  | * 38 |  5  | - red color background
====================================
|10:50 | Xyz  |   Xxx | * 55 | 65  | - red color background
====================================
|10:50 | asd  |   Xxx | 55   | 69  |
====================================
|12:50 | Kate |   Uh  | 35   | 62  |
====================================
|15:50 | Maria|   Zzz | 38   | 67  |
====================================

我的HTML腳本php：

<div class="Xyz" style="width:800px;height:50px;">
<?php
print "<h1 align=\"left\"> </br></h1>";
$file = fopen("File3.txt", "r");
while (false !== ($line = fgets($file))) {
$wynik=explode("+",$line);
$wynik=array_slice($wynik,0,10);
$grid=pc_grid_horizontal($wynik,10);
print $grid;
}
function pc_grid_horizontal($array, $size) {
    $table_width = 100;
    $width = intval($table_width / $size);
    $tr = '<tr align="center">';
    $td = "<td width=\"$width%%\">%s</td>";
    $grid = "<table border=1 cellspacing=0 width=\"$table_width%\">$tr";
    $i = 0;
    foreach ($array as $e) {
        $grid .= sprintf($td, $e);
        $i++;
        if (!($i % $size)) {
            $grid .= "</tr>$tr";
        }
    }

    while ($i % $size) {
        $grid .= sprintf($td, '&nbsp;');
        $i++;
    }
    $end_tr_len = strlen($tr) * -1;
    if (substr($grid, $end_tr_len) != $tr) {
        $grid .= '</tr>';
    } else {
        $grid = substr($grid, 0, $end_tr_len);
    }
    $grid .= '</table>';

    return $grid;
}
?>

請幫我。

為什么不簡單一些？ 您實際上不需要使用古老的HTML屬性為整個表格設置樣式。 您可以從外部樣式表使用css。

例如：

<?php
$file = file('File3.txt');

$table = array();
foreach($file as $line=>$content) {
   $parts = explode('|', $content); // turn your single line into an array of fields
   $parts = array_map('trim',$parts); // trim off any spaces from all parts
   if($line == 0) {
      $class = 'header'; // class for the header, that is the first line of the table
   } elseif($parts[3][0] == '*') {
      $class = 'emphasis'; // class for a row that needs to be red
   } else {
      $class = ''; // no class usually
   }
   $table[] = '<tr class="'.$class.'"><td>' . implode('</td><td>', $parts) . '</td></tr>';
}

echo '<table id="yourTbl">', implode("\r\n", $table), '</table>';

然后添加包含以下內容的CSS：

table#yourTbl {
   width: xx px; /* set to whatever width you want the table to be. If you wrap it in a <div> with a fixed with, you can change this one to 100% */
}
#yourTbl td {
   /* default style for all table data fields. Overwritten for specific fields in the next 2 definitions */
   text-align: center; /* make sure all values are centered inside the table */
}
/* your first row, with the table heading */
#yourTbl tr.header td {
   font-weight: bold;
}
/* your row with emphasis, which contains a * */
#yourTbl tr.emphasis td {
   color: red;
}
