创建多个数组的数组之一

Question

There are three array of the form:

Array (
    [0] => NAME
    [1] => NAME
    [n] => n
)
Array (
    [0] => DATE
    [1] => DATE
    [n] => n
)
Array (
    [0] => TEXT
    [1] => TEXT
    [n] => n
)

As possible to combine these three arrays in one of the next species?

Array(
    Array (
        [0] => NAME
        [1] => DATE
        [2] => TEXT
    )
    Array (
        [0] => NAME
        [1] => DATE
        [2] => TEXT
    )
        Array (
        [0] => NAME
        [1] => DATE
        [2] => TEXT
    )
    and etc.
)

Arrays build with the use of library PHP Simple HTML DOM Parser Manual that's the way

// Search for the name
$array_nameNews = array();
foreach($html->find('div.narrow_column div h2 a') as $element) {    
    $nameNews = $element->innertext;
    $array_nameNews[] = $nameNews;
}

// Search the date
$array_dateNews = array();
foreach($html->find('div.narrow_column div div.postdate') as $element) {
    $dateNews = $element->innertext;
    $array_dateNews[] = $dateNews;
}

// Search text
$array_textNews = array();
foreach($html->find('div.narrow_column div div.postdate span') as $element) {
    $textNews = $element->innertext;
    $array_textNews[] = $textNews;
}

You can do this with array_merge() and your end-result arrays as others suggest, but you should do this instead:

$articles = array();
foreach($html->find('div.narrow_column div') as $art_elem) {
    $article = array(
        'name' => $art_elem->find('h2 a', 0)->plaintext,
        'date' => $art_elem->find('div.postdate', 0)->plaintext,
        'text' => $art_elem->find('div.postdate span')->innertext,
    );
    $articles[] = $article;
}

Two reasons:

1. It's much clearer what you are actually trying to accomplish.
2. It is less brittle. Suppose a particular 'div.narrow_column div' element lacks one of these fields? In this case, your three arrays might be different sizes, or the items in the array may not correspond to other ones with the same index. If you iterate the container elements once and grab the items you need within the $art_elem context, you can degrade gracefully even when some items are missing.
