Php将值插入到多维数组中

Ok, I'm parsing a html file using simple_dom_html and everything works fine. What I'm trying to do is to insert the values into a multi dimensional array.

Here's my code:

foreach ($html->find('li[class="searchFacetDimension"]') as $filtros) {
    foreach($filtros->find('div[class="dimensionContainer"] h4') as $titulo){
            echo $titulo->plaintext . "<br>";
        foreach($filtros->find('div[class="dimensionContainer"] ul li a') as $link){
            echo $link->plaintext . "<br>";
        }
        echo "<br>";
    }
}

It outputs:

Category 1

  • sub 1

  • sub 2

Category 2

  • sub 1

What I'm trying to do is output it as an array, something like:

Array
(
    [0] => Array
        (
            [cat] => Category 1
            [subs] => Sub 1, Sub 2
        )

    [1] => Array
        (
            [cat] => Category 2
            [subs] => Sub 1
        )

)

    Here is the code you need:

    $result = array();
    foreach ($html->find('li[class="searchFacetDimension"]') as $filtros) {
        $aux = array()
        foreach($filtros->find('div[class="dimensionContainer"] h4') as $titulo){
                //echo $titulo->plaintext . "<br>";
                $aux['cat'] = $titulo->plaintext;
            foreach($filtros->find('div[class="dimensionContainer"] ul li a') as $link){
                //echo $link->plaintext . "<br>";
                $aux['subs'][] = $link->plaintext;
            }
            //echo "<br>";
        }
        $aux['subs'] = implode(", ",$aux['subs']);
        $result[] = $aux;
    }
    echo "<pre>";
    print_r($result);
    echo "</pre>";
