Are there any specific considerations or limitations when working with remote files in PHP?

When working with remote files in PHP, it is important to consider that some functions may not work with URLs and may require the file to be downloaded locally before processing. Additionally, there may be limitations on the size of files that can be downloaded or accessed remotely. To work around these limitations, you can use functions like file_get_contents() to download the remote file to a local temporary file before processing it. 

// Download remote file to local temporary file
$remoteFile = 'http://example.com/remote-file.txt';
$tempFile = tempnam(sys_get_temp_dir(), 'remote_file');
file_put_contents($tempFile, file_get_contents($remoteFile));

// Process the local temporary file
$data = file_get_contents($tempFile);

// Clean up the temporary file
unlink($tempFile);
