Can you confirm one thing Zachary Anderson , is it possible to use ssh2 in php or perl while using sawtooth hosting.

I am actually able to store audio file inside of hosting space. But I want to send the audio file to somewhere else using SFTP (ssh2) mainly. So is it possible to use ssh2 extension of php or I think perl has something like

``` use Net::SFTP::Foreign; ```

So basically I am using a post method with xhr to send a formdata like this

var formdata1 = new FormData();

formdata1.append('audio_file',blob,'audio.ogg');

xhr.send(formdata1);

so the php file can read the formdata1 as

$audioData = file_get_contents($_FILES['audio_file']['tmp_name']);

From here on I need ssh2 or SFTP to then upload the audioData to somewhere.

I have tried a php code like this but it return 500 internal server error to xhr.status

<?php\n// Get the file data\n$audioData = file_get_contents($_FILES['audio_file']['tmp_name']);\n\n// Specify the target directory and file name\n$targetDirectory = '/path/to/your/remote/directory/';\n$cleanedrespnum = $_POST['cleanedrespnum']; // Assuming cleanedrespnum is passed from FormData\n$questionID = $_POST['questionID']; // Assuming questionID is passed from FormData\n$iteration = 1;\n$targetFileName = $cleanedrespnum . '_' . $questionID . '_audio.ogg';\nwhile (file_exists($targetDirectory . $targetFileName)) {\n    $iteration++;\n    $targetFileName = $cleanedrespnum . '_' . $questionID . '_Audio' . $iteration . '.ogg';\n}\n\n// Connect to SFTP server\n$ssh = ssh2_connect('your-ssh-host', your-ssh-port);\nssh2_auth_password($ssh, 'your-ssh-username', 'your-ssh-password');\n\n// Initialize SFTP session\n$sftp = ssh2_sftp($ssh);\n\n// Specify the remote file path\n$remoteFilePath = 'sftp://' . $sftp . $targetDirectory . $targetFileName;\n\n// Write the file data to the target file\nif (file_put_contents($remoteFilePath, $audioData) !== false) {\n    echo 'File uploaded successfully: ' . $targetFileName;\n} else {\n    echo 'Error uploading file!';\n}\n?>

what is the maximum amount of string character i can store in a variable
