在PHP中，使用simplexml_load_file＆foreach遍历所有xml节点和子节点

Question

Given this XML document

My code:

    $xml = simplexml_load_file($url);
    $table = array();
    foreach ($xml->entry as $item) {
        foreach ($item->summary->div->blockquote as $block) {

                $element = array();
                $element['title'] = $block->p;
                $element['updated'] = strtotime($item->updated, time());
                $table[$element['updated']] = $element;

        }
    }

I want to insert all "p" values of the "blockquote" node and put them into an array. But it only gets the last "blockquote" node, not all.

I get this:

Warning: Invalid argument supplied for foreach() on line foreach ($item->summary->div->blockquote as $block) {

I need help.

This part of code:

$element['updated'] = strtotime($item->updated, time());

Seems to be always the same for all the elements and that may be overriding all the array.

Your $item seems to be always the same inside your second loop.
