重複數據從文件

所以我從有我有不同的電腦電腦1個表產品信息的文本文件中讀取顯示錶1是從文件1讀取，計算機2顯示錶2是從讀文件2，等等等等，但對於從表2中的某些原因，電腦3 & 4展會信息，並3 & 4我還沒有一點頭緒什麼在希望我的代碼可以提供更好的視野去。重複數據從文件

表1

$fp = fopen('key_QA_N1.txt','r'); 
if (!$fp) {echo 'ERROR: Unable to open file.</table></body></html>'; exit;} 

while (!feof($fp)) { 
    $line = fgets($fp,1024); //use 2048 if very long lines 
    $row++; 
    list ($products,$types, $keys, $date) = explode('|', $line); 
    if ($sortby == 'Products') $sortkey = strtolower($products);

嘗試在每節的開頭添加$col = array();。

你的意思是重置陣列內容$山坳=陣列（）; – 2010-11-29 13:07:26

感謝。我一直在使用Ruby過長：P – rwilliams 2010-11-29 13:08:25

我敢打賭，這是什麼Limpep建議，但我會提出一個更好的解決方案：

error_reporting(E_ALL^E_NOTICE); 
// create a wrapper function to prevent duplicate code! 
function displayQANFile($fname, $sortby = '') 
{ 
    $col = array(); 
    // NOTE: $row, $loop, and $arrays are no longer needed. 
    echo '<h1><span class="sortby"></span></h1> 
    <table cellspacing="5" summary="QA Tables"> 
    <tr> 
    <th>Products</th> 
    <th>Types</th> 
    <th>Keys</th> 
    <th>Date & Time Added</th> 
    </tr>'; 

    $fp = fopen($fname,'r'); 
    if (!$fp) {echo 'ERROR: Unable to open file ' . $fname . '.</table></body></html>'; exit;} 

    while (!feof($fp)) { 
     $line2 = fgets($fp,1024); //use 2048 if very long lines 
     list ($products2,$types2, $keys2, $date2) = explode('|', $line2); 
     if ($sortby == 'Products') $sortkey = strtolower($products2); 
     if ($sortby == 'Types') $sortkey = strtolower($types2); 
     if ($sortby == 'Keys') $sortkey = strtolower($keys2); 
     if ($sortby == 'Date & Time Added') $sortkey = strtolower($date2); 
     // did you mean to call array_sort on col at some point? 
     $col[] = array($sortkey, $products2, $types2, $keys2, $date2); 
    } 
    fclose($fp); 

    foreach($col as $row) { 
     echo ' 
    <tr> 
    <td>'.$row[1].'</td> 
    <td>'.$row[2].'</td> 
    <td>'.$row[3].'</td> 
    <td>'.$row[4].'</td> 
    </tr>'; 
    } 

    echo ' 
    </table> 
    '; 
} 
displayQANFile('key_QA_N1.txt'); 
displayQANFile('key_QA_N2.txt'); 
displayQANFile('key_QA_N3.txt'); 
displayQANFile('key_QA_N4.txt');

這種方式，你可以肯定，你不會有一個變量覆蓋另一個你可以防止所有這些重複的代碼......
