PHP Question

How do I print all the first values of an array's array in PHP?

I am using the 'PHP Simple HTML DOM Parser' library.
My code basically loops through my different sites and lists all the relevant anchors I need, my question is: how do I print the 1st value of the

href
in the anchor of the "selector" in each of the
$memb(n)
variables in the array of
$team
.

This is my code:

$memb1 = 'http://www.xyz1.org';
$memb2 = 'http://www.abc3.org';
$memb(n) = '...etc...etc'

$teams = array(
array("url" => $memb1, "selector" => ".product-list >
table:nth-child(1) >
tbody:nth-child(1) >
tr:nth-child(2) >
td:nth-child(2) > a"),
array("url" => $memb2, "selector" => ".product-list >
table:nth-child(1) >
tbody:nth-child(1) >
tr:nth-child(2) >
td:nth-child(2) > a"),
array("url" => $memb(n), "selector" => ".product-list >
table:nth-child(1) >
tbody:nth-child(1) >
tr:nth-child(2) >
td:nth-child(2) > a"),...etc...etc


When running the foreach loop like this:

foreach($teams as $site) {
$url = $site["url"];
$html = file_get_html($url);
foreach ($html->find($site["selector"]) as $a) {
$links[] = $a->href;
}
}
?>
<pre>
<?php print_r($links);?>
</pre>


I get all the selected anchors I wanted from all the
$memb
variables all together, yet i'm trying to print the 1st value of the href in the anchor of the "selector" in each of the
$memb(n)
variables in the array of
$team
, yet I can't find a way to do this.

I already tried
print_r(array_values($links)[0]);
yet I get only the 1st anchor from
$memb1
and it stops there, it doesn't continue to print the first anchor of
$memb2
and so on.

How can I print the 1st anchor (index 0) from every different $memb site?

Answer

If I get you right, than try this:

foreach($teams as $site) {
    $url = $site["url"];
    $html = file_get_html($url);
    foreach ($html->find($site["selector"]) as $a) {
        $links[] = $a->href;
        break;
    }
}
