PHP 将每个段落拆分为数组

Question

我想将每个段落拆分到一个数组中。

我目前的方法行不通:

$paragraphs = preg_split( '|</p>|', $text, PREG_SPLIT_OFFSET_CAPTURE );

---

我怎样才能从中得到:

$text = <<<TEXT
        <p>Hello!</p>
        <p style="border: 1px solid black;">How are you,<br /> today?</p>
TEXT;

对此

$paragraphs = array(
     '<p>Hello!</p>',
     '<p style="border: 1px solid black;">How are you,<br /> today?</p>'
);

Answer 1

您可以像下面这样使用 DOMDocument()

 <?php
$text = <<<TEXT
    <p>Hello!</p>
    <p style="border: 1px solid black;">How are you,<br /> today?</p>
TEXT;

$dom = new DOMDocument();
$paragraphs = array();
$dom->loadHTML($text);
foreach($dom->getElementsByTagName('p') as $node)
{

    $paragraphs[] = $dom->saveHTML($node);

}
print_r($paragraphs);
?>

输出

Array
(
  [0] => <p>Hello!</p>
  [1] => <p style="border: 1px solid black;">How are you,<br> today?</p>
)
