Php動態頁面分頁

所以我有這個頁面列出網站上的'.txt'文件內容。我試圖分頁，但它不起作用。我想每頁只有一個故事（一個故事是數據[0] .data [1]）該頁面通過ajax調用到瀏覽器。這裏是我的代碼：Php動態頁面分頁

<?php 
$dataArray = array(); 
//Number of chars for the string 
$num = 500; 
$dir = '../php/biralas_tortenetek/'; 
$willcount = readdir(opendir($dir)); 
$totfiles = count(readdir(opendir($dir))); 
//Check if </div>DIR e</div>xists 
if ($handle = opendir($dir)) { 
    //Loop over the directory 
    while (false !== ($file = readdir($handle))) { 
     //Strip out the . and .. files 
     if ($file != "." && $entry != "..") { 
      //Store file contents 
      $filecontent = file_get_contents($dir . $file); 
      //Split the content and store in array 
      $length = strlen($filecontent); 
      $dataArray[] = array(substr($filecontent, 0, $num), substr($filecontent, $num, $length)); 

     } 
    } 
    //close the dir 
    closedir($handle); 
} 


?><?php 
$page = isset($_GET['page']) ? $_GET['page']-1 : 0; 
echo "<br/>"; 
for($x=$page*1; $x < $totfiles && $x < ($page+1)*12; $x++) 
{ 
    foreach($dataArray as $data) { ?> 
     <div class="visible"> 
      <?php echo $data[0] . $data[1]; ?> 
     </div><?php } ?> 
</div> 
<?php } 
for($page=1; ($page-1)*12 < $totfiles; $page++) 
{ 
    echo "<div class='lapozo'><a onclick='story_changepage($page);' href='../html/blog.php#tortenetek?page=$page'>$page</a></div>"; 
} 
?>

所以，再一次，我們的目標是讓每個頁面只有一個故事。謝謝！

「我試圖進行分頁，但它不工作」，是什麼不起作用？任何錯誤？ – Tomer 2012-07-05 12:08:05

它只顯示1頁（這是正確的，因爲它設置爲顯示12層），當我點擊它時，它複製當前頁面。我試圖將它設置爲1個故事/頁面，但沒有成功。 – trisztann 2012-07-05 12:30:33

1解決方法：

$willcount = readdir(opendir($dir)); 
$i = 0; 
//Check if </div>DIR e</div>xists 
if ($handle = opendir($dir)) { 
    //Loop over the directory 
    while (false !== ($file = readdir($handle))) { 
     //Strip out the . and .. files 
     if ($file != "." && $entry != "..") { 
      //Store file contents 
      $filecontent = file_get_contents($dir . $file); 
      //Split the content and store in array 
      $length = strlen($filecontent); 
      // store file as indexed item of array 
      $dataArray[$i++] = array(substr($filecontent, 0, $num), substr($filecontent, $num, $length)); 
     } 
    } 
    //close the dir 
    closedir($handle); 
} 
// store total files in dir 
$totfiles = $i; 

$page = isset($_GET['page']) ? $_GET['page']-1 : 0; 
echo "<br/>"; 

for($x=$page*12; $x < $totfiles && $x < ($page+1)*12; $x++) { 
    $data = $dataArray[$x]; 
    ?> 
     <div class="visible"> 
      <?php echo $data[0] . $data[1]; ?> 
     </div> 
<?php 
}

CUT第二個解決方案：//者優先它使用較少的內存比1解決方案

$willcount = readdir(opendir($dir)); 
$i = 0; 
// get page 
$page = isset($_GET['page']) ? $_GET['page']-1 : 0; 

//Check if </div>DIR e</div>xists 

if ($handle = opendir($dir)) { 
    //Loop over the directory 
    while (false !== ($file = readdir($handle))) { 
     //Strip out the . and .. files 
     if ($file != "." && $entry != "..") { 
      $i ++; 
      // if our page not first, skip add 
      if ($i <= $page * 12) continue; 
      // if we reach end of the page, break 
      if ($i > ($page + 1)* 12) break; 
      //Store file contents 
      $filecontent = file_get_contents($dir . $file); 
      //Split the content and store in array 
      $length = strlen($filecontent); 
      $dataArray[] = array(substr($filecontent, 0, $num), substr($filecontent, $num, $length)); 
     } 
    } 
    //close the dir 
    closedir($handle); 
} 
// store total files in dir 
$totfiles = $i; 

echo "<br/>"; 

foreach($dataArray as $data) { 
    ?> 
     <div class="visible"> 
      <?php echo $data[0] . $data[1]; ?> 
     </div> 
<?php 
}
