这是我想要做的一个例子 例如:
<div class='room'>
<h1>This is a h1</h1>
<p>This is a Paragraph</p>
<h2>This is h2</h2>
</div>
从上面的emaple我想废弃数组中的数据和标签。 在结果中我想要一个包含以下内容的数组: arr = [h1,p,h2]; 和另一个数组: arr2 = [这是h1,这是段落,这是h2]

假设元素已知,您可以使用domdocument&#39; s getelementsbytagname,如下所示:
usort($string_content_to_explode,function($a,$b){
if ($a[1] == $b[1])
return 0;
return ($a[1] < $b[1])? -1: 1;
});
var_dump($string_content_to_explode);

试试这个;
$str = "<div class='room'>
<h1>This is a h1</h1>
<p>This is a Paragraph</p>
<h2>This is h2</h2>
</div>";
$arr = explode(PHP_EOL, $str);
$res =array();
Foreach($arr as $row){
If(!strpos($row, "div") !== False){
$res[substr($row, 1, strpos($row, ">")-1)] = strip_tags($row);
}
}
Var_dump($res);
它一直循环一行,并使用命名键创建数组。
编辑如果有多个房间,你可以像这样多维:

$str = "<div class='room'>
<h1>This is a h1</h1>
<p>This is a Paragraph</p>
<h2>This is h2</h2>
</div>
<div class='room2'>
<h1>This is a h1</h1>
<p>This is a Paragraph</p>
<h2>This is h2</h2>
</div>";
$arr = explode(PHP_EOL, $str);
$res =array();
Foreach($arr as $row){
If(strpos($row, "div") !== False){
$pos1 = strpos($row, "'")+1;
$room = substr($row, $pos1, strpos($row, "'", $pos1)-$pos1);
}Else{
$pos1 = strpos($row, "<")+1;
$res[$room][substr($row, strpos($row, "<")+1, strpos($row, ">")-$pos1)] = trim(strip_tags($row));
}
}
Var_dump($res);

尝试以下代码。
$html = "<div class='room'>
<h1>This is a h1</h1>
<p>This is a Paragraph</p>
<h2>This is h2</h2>
</div>";
$dom = new SimpleXMLElement( $html );
$values = array_filter( array_values( (array) $dom ), function ( $i ) { return ! is_array( $i ); } );
$keys = array_filter( array_keys( (array) $dom ), function ( $i ) { return $i != '@attributes'; } );
print_r( $values ); // This is a h1, This is a Paragraph, This is h2
print_r( $keys ); // h1, p, h2
我使用array_filter
从结果中删除div标记。

$str = <<<EOF
<div class='room'>
<h1>This is a h1</h1>
<p>This is a Paragraph</p>
<h2>This is h2</h2>
</div>
EOF;
$html = str_get_html($str);
foreach($html->find('.room *') as $el){
$arr[] = $el->tag;
$arr2[] = $el->text();
}
