PHP Simple HTML DOM list of attributes

问题

The simple_html_dom library is great for getting known attributes, but is there a way to get a list of all the attributes for an element?

For example, if I have:

<div id="test" custom1="custom" custom2="custom">

I can easily get the id:

$el = $html->find('div');
$id = $el->id;

But, is it possible to get custom1 and custom2 if they are not known ahead of time? Ideally, the solution would produce an array of the NVP's for all attributes (id, custom1, custom2).

回答1:

$el->attr is an associated array of tag=>value s

回答2:

You can use get_object_vars to get an associative array, and then loop over them.

$attrs = get_object_vars($el);

foreach($attrs as $key=>$value) {
}
