分頁和foreach循環Amazon S3的

我試圖實現與Amazon S3的分頁，是他們的一種方式時，當它完成了一個foreach開始，我可以設置？分頁和foreach循環Amazon S3的

示例我從amazon獲得以下輸出。這是我的print_r（$ files）的輸出;

我想從foreach中的第4個元素開始，並停在第6個只顯示那些inbetween。

$i = 0; 

$start = 4; 

$stop = 6; 

    foreach($files as $v){ 

     if (++$i == $start) 

    echo $v['name']; 

     if (++$i == $stop) break; 

    }

有人可以請幫助我如何實現這???

這是非常醜陋的，但它可以工作（如果你想顯示的項目4和5）：

reset ($files); 
for($i = 0; $i < 3; $i++) { 
    next($files); 
} 
for ($i = 0, $current = current($files); $i < 2 && false !== $current; $i++, $current = next($files)) { 
    echo $current['name']; 
}

你可以使用這個如果你是一個骯髒的編碼器！我認爲你可以對迭代器做一些美事。

編輯：或者你也可以試試這個：（更像是你的代碼位）

$i = 0; 
$start = 4; 
$stop = 6; 
foreach($files as $v){ 
    if (++$i >= $start) echo $v['name']; 
    if ($i == $stop) break; 
}

你必須讓你的限制器的動態。您還需要2個不同的分頁計數器。一個計數器從零開始......下一個從PAGE *結果開始。這兩個需要每個循環都加1：

$c=0; 
$p=$_GET[page] * 25; 
$l=$p + 25; 
foreach($array as $obj){ 
$c++; $p++; 
if ($p==$l) break; 
if ($c>$p) echo $obj; 
}
