What are the common pitfalls to avoid when reading data from a socket in PHP?

Common pitfalls to avoid when reading data from a socket in PHP include not checking for errors, not handling incomplete data reads, and not properly closing the socket after reading. To address these issues, always check for errors when reading from a socket, handle cases where the data read may be incomplete, and ensure to close the socket properly to prevent resource leaks. 

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, '127.0.0.1', 8080);

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

if ($data === false) {
    // Handle error when reading data
} else {
    // Process the data read from the socket
}

socket_close($socket);
