Looping through a multidimensional array with PHP - php

Question

I'm trying to learn php and talk to an API to retrieve info for my Destiny 2 clan. I've retrieved all the info that I needed and build a new array with the following format:
Array
(
[displayname] => Senaxx
[membershipId] => 4611686018428643772
[characterdetails] => Array
(
[0] => Array

[characterlevel] => 30
[light] => 384

[minutesplayed] => 14901

These are only 2 player arrays. My whole code has 8. But for this example I think 2 of them will suffice.
My goal is to loop trough the array and retreive all the player info for each displayname.
So i started with which works perfectly:
foreach($claninfo as $clanmember)
{
echo $clanmember['membershipId'];
}
Only grabbing the characterdetails doesn't work for me sadly enough.
The problem for mee seems that there is an extra characterId with an unknown number.
foreach($claninfo as $clanmember)
{
echo $clanmember['membershipId'];
foreach($claninfo->characterdetails as $characterdetails)
{
echo $characterdetails-> light;
}
}
Ultimate goal is to have a table with some of the info in it:
<table>
<tbody>
<tr>
<td>Displayname</td>
<td>Playtime</td>
<td>Character 1</td>
<td>Character 2</td>
<td>Character 3</td>
</tr>
<tr>
<td>Senaxx</td>
<td> </td>
<td>light 384</td>
<td>light 394</td>
<td>light 394</td>
</tr>
<tr>
<td>Base1981</td>
<td> </td>
<td>light 358</td>
<td>light 100</td>
<td>light 350</td>
</tr>
</tbody>
</table>

Answer 1

The associative array key for till the light is:
$claninfo[<some key or index>]['characterdetails'][<Array Index>][<character id>]['light']
So to access light you need to use foreach 3 times:
To get clanmember from claninfo
To iterate $clanmember['characterdetails']
To get rid of character id
foreach($claninfo as $clanmember)
{
echo $clanmember['membershipId'];
foreach($clanmember['characterdetails'] as $characterArray)
{
foreach($characterArray as $characterid => $characterdetails)
{ // You can access $characterid in this block
echo $characterdetails['light'];
}
}
}

Answer 2

characterdetails is an array and not an object.
You can loop through the array using the following code
foreach($claninfo as $clanmember)
{
echo $clanmember['membershipId'];
foreach($claninfo['characterdetails'] as $characterdetails)
{
echo $characterdetails['light'];
}
}

Answer 3

It looks like there are 3 different problems with your code. You are working on arrays, you should not use object notation (->) at all. You use the wrong array in your inner foreach. Third, and this is probably your real question, you need a way to access a key that you don't know (unknown id). That last one can be circumvented for example with array_values (manual). All together:
foreach($claninfo as $clanmember)
{
echo $clanmember['membershipId'];
foreach($clanmember['characterdetails'] as $characterdetails)
{
echo array_values($characterdetails)[0]['light'];
}
}

Answer 4

My final solution was:
foreach($claninfo as $clanmember)
{
echo '<br><b>' . $clanmember['displayname'] . '</b><br>' ;
foreach($clanmember['characterdetails'] as $characterArray)
{
$characterId = $characterArray['characterId'];
$characterlight = $characterArray['light'];
$characterlevel = $characterArray['characterlevel'];
$characterlastplayed = $characterArray['datelastplayed'];
$characterminutesplayed = $characterArray['minutesplayed'];
$characterracehash = $characterArray['racehash'];
$charactergenderhash = $characterArray['genderhash'];
$characteremblempath = $characterArray['emblempath'];
$characteremblemhash = $characterArray['emblemhash'];
echo 'CharacterId: ' . ($characterId) . '<br>';
echo 'Light: ' . ($characterlight) . '<br>';
echo 'level: ' . ($characterlevel) . '<br>';
echo 'Last Played: ' . ($characterlastplayed) . '<br>';
echo 'Minutes Played: ' . ($characterminutesplayed) . '<br>';
echo 'RaceHash: ' . ($characterracehash) . '<br>';
echo 'GenderHash: ' . ($charactergenderhash) . '<br>';
echo 'Emblempath: ' . ($characteremblempath) . '<br>';
echo 'Emblemhash: ' . ($characteremblemhash) . '<br>';
echo '<br>';
}
}
