phpQuery usage error resolution

phpQuery is a server-side implementation of jQuery php version. It can query and operate the read documents (from local files or URLs) using syntax similar to jQuery, which is very convenient.

It is very useful for information collection, but of course it also generates a lot of duplicate information

I encountered another problem this time. After querying the loop list of a certain div using class method, I want to use array Ways to save certain fields in a div, such as:

$doc = \phpQuery::newDocumentFile('C:/xampp/htdocs/sae/st/text.htm');
$piclist = pq(".p-cell.cellItem");
foreach ($piclist as $pic) {
    $picurl = pq($pic)->find('.pic img')->attr('src');
    $pictitle = pq($pic)->find('span.cellTit')->html();
    //以下两行会报错 Cannot use object of type DOMElement as array    
    $pic['src'] = $picurl;
    $pic['name'] = $pictitle;  
    //正确的使用方式， 参见 http://www.wallpaperama.com/forums/howto-fix-fatal-error-cannot-use-object-of-type-stdclass-as-array-in-php-t1735.html
    //$pic->name = $pictitle;
    //$pic->src  = $picurl;
}
