Question

这是我的字符串。

$list = '
<div id="list">
   <div class="item">foo: bar</div>
   <div class="item">name: value</div>
   <div class="item">color: red</div>
   <div class="item">count: 1</div>
</div>
';

如何从这个html获取数据并添加到PHP数组的最佳方法？我想收到：

$items = array('foo' => 'bar', 'name' => 'value', 'color' => 'red', 'count' => 1);

Answer 1

使用DOMDocument和DOMXpath解析html并获取内容然后，您可以在$str = <<<EOF <div id="list"> <div class="item">foo: bar</div> <div class="item">name: value</div> <div class="item">color: red</div> <div class="item">count: 1</div> </div> EOF; //Parse the html data $dom = new DOMDocument; $dom->loadHTML($str); $xpath = new DOMXpath($dom); //Get only those divs which have class=item $div_list = $xpath->query('//div[@class="item"]'); $content_arr = []; foreach($div_list as $d){ $c = explode(": ", $d->nodeValue); $content_arr[$c[0]] = $c[1]; } var_dump($content_arr);上拆分它们并将它们添加到数组中像这样的东西 -

array(4) {
  'foo' =>
  string(3) "bar"
  'name' =>
  string(5) "value"
  'color' =>
  string(3) "red"
  'count' =>
  string(1) "1"
}

此输出 -

{{1}}

Answer 2

var arr = [];
$('.item').each(function(){

   var asdf = $(this).text();
   var qwerty = asdf.split(":");
      arr.push(qwerty['0'] + ' =>' + qwerty['1']); 
});

alert(arr);

希望这可以帮助你.. =）

您可以使用SimpleXML执行此操作。为此你需要像这样编码：

<?php
$html='<div id="list">
   <div class="item">foo: bar</div>
   <div class="item">name: value</div>
   <div class="item">color: red</div>
   <div class="item">count: 1</div>
</div>';

$xml = new SimpleXMLElement($html);

$result = $xml->xpath('//div[@id="list"]');
$items = array();
foreach($result AS $arrKeys => $arrValue){
        foreach($arrValue AS $innerValue){
                list($key,$value) = explode(":",$innerValue);
                if(!empty($value)){
                        $items[$key] = $value;
                }
        }

}

print_r($items);
?>

这是您想要的一步一步的代码。
