Download a file from SharePoint OnLine using PHP

Question

I need to download a file in SharePoint Online from PHP.

The only data I have is the URL of the folder.

Access is public, does not require authentication.

How can you complete this task from PHP? Any API?

Thanks in advance.

Answer 1

I struggled with the same issue using phpSPO, found a direct way to download. Simply replace everything after the ? in the url with "download=1" src

$fileUrl    = "https://mycompany.sharepoint.com/folders/someGUIDlikeSTRING?download=1";
$filePath   = "/tmp/saveHere.file";
$strCmd     = "wget -O  " . $filePath . " " . $fileUrl;
shell_exec($strCmd);

Curl kept receiving a 403, while wget worked fine. Its a hackish shell call, obviously curl would be a better solution, but it works.

You can use phpSPO library (https://github.com/vgrem/phpSPO). It has 2 methods which can be used. below is snippet from another post on stackoverflow

function downloadFile(ClientRuntimeContext $ctx, $fileUrl, $targetFilePath){
    $fileContent = 
Office365\PHP\Client\SharePoint\File::openBinary($ctx,$fileUrl);
    file_put_contents($targetFilePath, $fileContent);
    print "File {$fileUrl} has been downloaded successfully\r\n";
}

function downloadFileAsStream(ClientRuntimeContext $ctx, $fileUrl, 
    $targetFilePath) {
    $fileUrl = rawurlencode($fileUrl);

    $fp = fopen($targetFilePath, 'w+');
    $url = $ctx->getServiceRootUrl() . "web/getfilebyserverrelativeurl('$fileUrl')/\$value";
    $options = new \Office365\PHP\Client\Runtime\Utilities\RequestOptions($url);
    $options->StreamHandle = $fp;
    $ctx->executeQueryDirect($options);
    fclose($fp);

    print "File {$fileUrl} has been downloaded successfully\r\n";
}
