Yes, it is possible to read a PHP file from an external server using fopen/fsockopen. You can use these functions to establish a connection to the remote server and then read the contents of the file. Make sure you have the necessary permissions to access the file on the remote server.

<?php
$remoteFile = 'http://www.example.com/file.php';
$handle = fopen($remoteFile, 'r');
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        echo $line;
    }
    fclose($handle);
} else {
    echo 'Error opening the file.';
}
?>
