How can socket connections be used to read the content of a script and store it in a variable?

To read the content of a script and store it in a variable using socket connections, you can establish a connection to the server hosting the script, send a request to retrieve the script content, read the response from the server, and store it in a variable. This can be achieved by using PHP's socket functions to create a TCP socket connection, send an HTTP GET request to the server, and read the response data. 

<?php
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$host = 'example.com';
$port = 80;

if(socket_connect($socket, $host, $port)) {
    $request = "GET /path/to/script.php HTTP/1.1\r\nHost: $host\r\n\r\n";
    socket_write($socket, $request, strlen($request));

    $response = '';
    while ($buffer = socket_read($socket, 1024)) {
        $response .= $buffer;
    }

    $scriptContent = substr($response, strpos($response, "\r\n\r\n") + 4);
    echo $scriptContent;

    socket_close($socket);
} else {
    echo "Failed to connect to server";
}
?>
