Are there any alternative methods to move_uploaded_file() for uploading files between domains in PHP?

When using the move_uploaded_file() function in PHP to upload files between domains, you may encounter issues due to security restrictions. One alternative method is to use cURL to transfer the file from one domain to another. This can be achieved by sending a POST request with the file contents as the request body. 

// Source file URL
$source_url = 'https://www.example.com/source_file.jpg';

// Destination URL
$destination_url = 'https://www.example2.com/upload.php';

// Get file contents
$file_contents = file_get_contents($source_url);

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $destination_url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $file_contents);

// Execute cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Check for errors
if($response === false){
    echo 'Error uploading file.';
} else {
    echo 'File uploaded successfully.';
}
