how to foreach 2 array

i use preg_match_all and get array like this

Array
(
    [1] => Array
        (
            [0] => link1
            [1] => link2
            [2] => link3
            [3] => link4
            [4] => link5
        )

    [3] => Array
        (
            [0] => title1
            [1] => title2
            [2] => title3
            [3] => title4
            [4] => title5
        )

)

I tried using array_merge, but that's not what I wanted

i want the foreach return like this

<a href="link1" class=list-group-item> title1</a>
<a href="link2" class=list-group-item> title2</a>
<a href="link3" class=list-group-item> title3</a>
<a href="link4" class=list-group-item> title4</a>
<a href="link5" class=list-group-item> title5</a>

How can i do that???

To loop two arrays together independent of its indexes use such construction

foreach(array_map(null, ...$arr) as [$link,$title]) {
   echo "<a href='$link' class=list-group-item> $title</a>";

Before PHP 7 you need rewrite it to as list($link,$title)

$keys=$array[1];

$values=$array[3];


$combines=array_combine($keys,$values);
foreach($combines as $key=>$value)
{
   echo '<a href="'.$key.'" class=list-group-item> '.$value.'</a>';

}

First, reset the keys of your main array.

$array = array_values($array);

Next, loop through one set of your data, in my example I will use the first set of data. Inside the loop, you can grab the 2nd set of data using the key from the first set.

foreach($array[0] as $key => $href) {
    $title = $array[1][$key];
    echo "<a href='$href' class=list-group-item> $title</a>";
}

This will only work if you always receive 2 sets of data that are the same length.

If you don't want to use that method for whatever reason, you could use array_shift();.

$links = array_shift($array); //grab first set from array, and remove it from array.
$titles = array_shift($array);

foreach($links as $key => $link) {
    $title = $titles[$key];
    echo "<a href='$link' class=list-group-item> $title</a>";
}
