我正在嘗試根據每個包裝塊的結果數添加一些自定義類。在每個包裝塊的最后一個添加類last。計算每個包裝塊的結果，并根據結果添加自定義類，one-half one-third one-fourth這是代碼：<?php$array = range(1, 11); $i= 0; foreach ($array as $val) { if ($i%4 == 0) echo '<div class="item">'; $i++;?> <span class="one-fourth"><?=$val?></span><?php if ($i%4 == 0) echo '</div>'; } if ($i%4 != 0) echo '</div>';?>我得到的輸出：<div class="item"> <span class="one-fourth">1</span> <span class="one-fourth">2</span> <span class="one-fourth">3</span> <span class="one-fourth">4</span></div><div class="item"> <span class="one-fourth">5</span> <span class="one-fourth">6</span> <span class="one-fourth">7</span> <span class="one-fourth">8</span></div><div class="item"> <span class="one-fourth">9</span> <span class="one-fourth">10</span> <span class="one-fourth">11</span></div>我想要的輸出：<div class="item"> <span class="one-fourth">1</span> <span class="one-fourth">2</span> <span class="one-fourth">3</span> <span class="one-fourth last">4</span></div><div class="item"> <span class="one-fourth">5</span> <span class="one-fourth">6</span> <span class="one-fourth">7</span> <span class="one-fourth last">8</span></div><div class="item"> <span class="one-third">9</span> <span class="one-third">10</span> <span class="one-third last">11</span></div>

這可能最容易通過將數組拆分為塊并在循環中單獨處理每個塊，使用count塊的 來決定將哪個類添加到跨度：
$array = range(1, 11);
$chunks = array_chunk($array, 4);
$span_classes = ['', 'one-half', 'one-third', 'one-fourth'];
foreach ($chunks as $chunk) {
echo "<div class=\"item\">\n";
$count = count($chunk);
$span_class = $span_classes[$count-1];
for ($i = 0; $i < $count; $i++) {
$last = $i == $count - 1 ? ' last' : '';
$val = $chunk[$i];
echo "<span class=\"$span_class$last\">$val</span>\n";
}
echo "</div>\n";
}
輸出：
<div class="item">
<span class="one-fourth">1</span>
<span class="one-fourth">2</span>
<span class="one-fourth">3</span>
<span class="one-fourth last">4</span>
</div>
<div class="item">
<span class="one-fourth">5</span>
<span class="one-fourth">6</span>
<span class="one-fourth">7</span>
<span class="one-fourth last">8</span>
</div>
<div class="item">
<span class="one-third">9</span>
<span class="one-third">10</span>
<span class="one-third last">11</span>
</div>
