How can PHP be used to continuously read from a named pipe and process the data?

To continuously read from a named pipe in PHP, you can use the `fopen` function to open the named pipe for reading and then use a loop to continuously read data from the pipe using `fgets` or `fread`. You can process the data as needed within the loop. It's important to properly handle any errors that may occur during the reading process.

$pipe = fopen('/path/to/named/pipe', 'r');
if (!$pipe) {
    die('Failed to open named pipe for reading');
}

while (true) {
    $data = fgets($pipe);
    if ($data === false) {
        // Handle error or break the loop if needed
        break;
    }

    // Process the data as needed
    echo $data;
}

fclose($pipe);
