<p>I have the following code for downloading files from Google Drive, the number of files is determined by nextPageToken as shown below. </p> <p>The code will continue adding arrays to the $files array until nextPageToken is null. At this point, I have an unknown number of sub-arrays and I wish to merge them into a single array without looping through all returned arrays - is there an easy way to achieve this using PHP? </p> <p>So, in the code below, I want $files[] to be a single array. For example: </p> <p><code>$result = array_merge($files); </code>will only produce the same result</p> <pre class="brush:php;toolbar:false;">``` $nextPageToken = "empty" ; while ( $nextPageToken != null) { $responseFiles = $drive->ListFiles( $optParams); $nextPageToken = $responseFiles->getNextPageToken(); $files[] = $responseFiles->getFiles(); $optParams = array( 'fields' => "nextPageToken, files(contentHints/thumbnail,fileExtension,iconLink,id,name,size,thumbnailLink,webContentLink,webView Link,mimeType,parents)", 'q' => "'".$match[0]."' in parents", 'pageToken' => $nextPageToken, 'orderBy' => 'modifiedTime desc, name' ); } ```</pre></p>

$files = [];
$nextPageToken = "empty";

$optParams = array(
    'fields' => "nextPageToken, files(contentHints/thumbnail,fileExtension,iconLink,id,name,size,thumbnailLink,webContentLink,webView Link,mimeType,parents)",
    'pageToken' => $nextPageToken,
    'orderBy' => 'modifiedTime desc, name'
);

while ( $nextPageToken != null) {
  $responseFiles = $drive->ListFiles($optParams);
  $nextPageToken = $responseFiles->getNextPageToken();
  $files = array_merge($files, $responseFiles->getFiles());
  $optParams['q'] => "'".$match[0]."' in parents";
}
