将php变量内容转换为html字符串

Question

I am parsing data from html using PHP Simple HTML DOM parser.

$html = file_get_html('www.example.com');
$e= $html->find('div[class=BodyContent]');

The variable $e contains html data (divs, imgs, etc). If I echo it on the screen with a foreach loop, it prints out on the screen perfectly. How can I convert this $e to a string? My goal is for it to look like this and use:

$x = str_get_html('<div id="BodyContent">Hello</div>
                   <div id="world">World</div>...otherData');

How can I do this so $e content displays as regular HTML inside str_get_html?

Update: The variable $e should contain HTML data after parsing:

<div id="BodyContent">
  <div id="somethingelse>
    <p>Some more content</p><a>Some links</a>
  <span></span>
</div>

The function from SimpleHtmlDom requires parameter 1 to be a string so...I want to convert the variable $e to a string so all these divs and paragraphs can be inserted into the str_get_html('HERE').

Answer 1

$e is an array or an object. Casting it to an array will ensure you can implode on it even if its a single object, then implode will call the __toString on all the objects giving you a single html string:

$htmlstr = implode("
", (array) $e);

The array casting could be overkill because in order to get just a single object as the return value from find you have to call it with a specific index - so presumably you would know whether to cast or not... but if you are juggling $e around a bunch it might be easier to just cast it like ive show so it doesnt blow up.

In that case you need to find the Method you want in the API and call it on each element... Id use array_map for this:

$htmlstr = implode("
", array_map(function ($node) { return $node->whatever; }), (array) $e);
