creating multidimensional array with two arrays - php

Question

I am indexing web pages. The code scans the web pages for links and the web page that is given's title. The links and title are stored in two different arrays. I would like to create a multidimensional array that has the word Array, followed by the links, followed by the individual titles of the links. I have the code, I just don't know how to put it together.
require_once('simplehtmldom_1_5/simple_html_dom.php');
require_once('url_to_absolute/url_to_absolute.php');
//links
$links = Array();
$URL = 'http://www.youtube.com'; // change it for urls to grab
// grabs the urls from URL
$file = file_get_html($URL);
foreach ($file->find('a') as $theelement) {
$links[] = url_to_absolute($URL, $theelement->href);
}
print_r($links);
//titles
$titles = Array();
$str = file_get_contents($URL);
$titles[] = preg_match_all( "/\<title\>(.*)\<\/title\>/", $str, $title );
print_r($title[1]);

Answer 1

You should be able to do this, assuming there are the same amount of links as there are titles, then they should correspond to the same array key.
$newArray = array();
foreach ($links as $key=>$val)
{
$newArray[$key]['link'] = $val;
$newArray[$key]['title'] = $titles[$key];
}

Answer 2

It is not clear what you want.
Anyway, here is how I would rewrite your code in a more organized way:
require_once('simplehtmldom_1_5/simple_html_dom.php');
require_once('url_to_absolute/url_to_absolute.php');
$info = array();
$urls = array(
'http://www.youtube.com',
'http://www.google.com.br'
);
foreach ($urls as $url)
{
$str = file_get_contents($url);
$html = str_get_html($str);
$title = strval($html->find('title')->plaintext);
$links = array();
foreach($html->find(a) as $anchor)
{
$links[] = url_to_absolute($url, strval($anchor->href));
}
$links = array_unique($links);
$info[$url] = array(
'title' => $title,
'links' => $links
);
}
print_r($info);
