Combine duplicate entries in array / foreach

I am trying to combine two entries either on the array level or foreach level (either would work fine)

Here is the code:

foreach ($objects['Contents'] as $object) {

    $_object_ = str_replace($prefix, '', $object['Key']);
    $_date_ = str_replace('+00:00', '', str_replace('T', ' ', $object['LastModified']));

    $folders = array();

    if (strpos($_object_, '/') !== false && substr($_object_, -1) != '/') {

        if (!in_array(strtok($_object_, '/'), $folders)) {
            array_push($folders, strtok($_object_, '/'));
        }

    } elseif (strpos($_object_, '/') !== false) {
        array_push($folders, str_replace('/', '', $_object_));
    }

    echo '<pre>';

    foreach($folders as $folder){
      echo $folder.'<br/>';
      if (strpos($_object_ , $folder.'/') !== false) {
        echo ' -'.str_replace($folder.'/', '', $_object_);
      }
    }

    echo '</pre>';

} 

Here is the output:

folder
 -
general
 -BMS-Shield.txt
general
 -image-2.jpg
planning
 -composer.json
test
 -

Here is the desired output:

folder

general
 -BMS-Shield.txt
 -image-2.jpg
planning
 -composer.json
test

Just for a bit of background I am trying to get a list of files from aws s3 and display the contents of each folder (‘folder’, ‘general’, ‘planning’ etc…) but when there is more than one file in a folder it prints the folder twice (as seen in output above).

Here is the file structure on s3:

I have tried the array_unique() function but this gave the same output.

Any help would be much appreciated.

Output of $objects[‘Contents’]:

Answer

You can do it by giving your $folders array the key as the folder name, and as the value an array of subfolders :

$objects = [
    [
        'Key' => 'dashboard/demo.consultive.test/user-data/nXb2K1feviqsjzuW7mgQG2Cghc1Kem8U/uploads/folder/',

            'date' => '2020-02-25 09:47:43.000000',
            'timezone_type' => '2',
            'timezone' => 'Z'
        ],
        'ETag' => 'd41d8cd98f00b204e9800998ecf8427e',
