php - 如何使用 implode 和 array_splice 结束句子？

Question

如果我们的内容中有 5 个句子，并且我们想将所有文本分成两个区域，我们将使用如下内容：

$content = 'Sentence number one. Sentence number two. Sentence number 3. Sentence number 4. Sentence number 5.';
$slices = explode(" ", $content);
$first_slice = implode(" ", array_splice($slices, 0, 10));
$second_slice = implode(" ", array_splice($slices, 0));
echo '<div class="first_slice">'. $first_slice .'</div>';
echo '<div class="second_slice">'. $second_slice .'</div>';

这个的输出是：

<div class="first_slice">Sentence number one. Sentence number two. Sentence number 3. Sentence</div>
<div class="second_slice">number 4. Sentence number 5.</div>

如何将开始的句子推到结束？在此示例中，如何获取输出：

<div class="first_slice">Sentence number one. Sentence number two. Sentence number 3. Sentence number 4.</div>
<div class="second_slice">Sentence number 5.</div>

Answer 1

您可以通过假设每个句子都以一个点和一个空格结尾来拆分句子。

<?php
$content = 'Sentence number one. Sentence number two. Sentence number 3. Sentence number 4. Sentence number 5.';
$sentences = explode(". ", $content);
$first_slice = array_slice($sentences, 0, 3);
$second_slice = array_slice($sentences, 3, 4);
?>

然后打印你想要的句子：

<div class="first_slice">
<?php
echo implode(" ", $first_slice);
?>
</div>
<div class="second_slice">
<?php
echo implode(" ", $second_slice);
?>
</div>
