apache_request_headers() get specific value with PHP

Question

I do a JSON call and return it With:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 
'https://www.example.com/sdfsldfsd3/all-result.json');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('AccessKey: 
dasdasdq312312qWQEQ'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$headers = apache_request_headers();

foreach ($headers as $header => $value) {
    echo "$header: $value <br />\n";
}  
$json = curl_exec($ch);
curl_close($ch);

Now I would like to display the first 5 values of title:

string(906287) "{"data":[{"id":12238,"title":"Title no 1"},{"id":7510,"title":"Title no 2"}, 
etc.

How am I supposed to display a result like:

<a href=page.php?id=12238>Title no 1</a> <br>
<a href=page.php?id=7510>Title no 2</a> <br> etc

Thanks in advance

Working code:

$json = curl_exec($ch);
$data = json_decode($json);

foreach ($data->data as $key => $row) {
    if ($key === 5) break; 
        echo '<a href=page.php?id=' . $row->id . '>' . $row->title . '</a> <br>';
    }
}

If you need to write down all links, use just

<?php

$str = '{"data":[{"id":12238,"title":"Title no 1"},{"id":7510,"title":"Title no 2"}]}';
$data = json_decode($str);

foreach ($data->data as $row) {
    echo '<a href=page.php?id=' . $row->id . '>' . $row->title . '</a> <br>';
}

If you need just 5 links, foreach would be

foreach ($data->data as $key => $row) {
    if ($key === 5) break;

    echo '<a href=page.php?id=' . $row->id . '>' . $row->title . '</a> <br>';
}
