从div列表获取文本到PHP数组

Question

Here is my string.

$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>
';

How is the best way to get data from this html and add to PHP array? I would like receive:

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

Answer 1

Use DOMDocument and DOMXpath to parse the html and get the contents.
You can then split them on : and add them to an array.
Something like this -

$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);

This outputs -

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