Looping problems socket programming in C

Sorry if I posted 2 separate questions.
I'm currently doing socket programming on my current task. As you can see below in the client side. I've tried to do a loop so I will be able to get prompt for input over and over again.
This is the code.

Code:
do{ 
 
    
   printf("Please your name > "); 
   scanf("%s",name); 
    
   write(clientFd,name,strlen(name)); 
 
    
   }while(strcmp("exit",name)!=0);

It worked for the first time, but the second time it asked me for input but it did not print anything on the server side. After entering the second input it exited from the terminal.

I've check up the loop and realize it was the write problem. Any way to solve this?

socket_set_block - Sets blocking mode on a socket resource

SYNOPSIS
bool socket_set_block (resource $socket) DESCRIPTION
The socket_set_block(3) function removes the O_NONBLOCK flag on the socket specified by the $socket parameter. When an operation (e.g. receive, send, connect, accept, ...) is performed on a blocking socket, the script will pause its execution until it receives a signal or it can perform the operation. PARAMETERS
o $socket - A valid socket resource created with socket_create(3) or socket_accept(3). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 socket_set_block(3) example <?php $socket = socket_create_listen(1223); socket_set_block($socket); socket_accept($socket); ?> This example creates a listening socket on all interfaces on port 1223 and sets the socket to O_BLOCK mode. socket_accept(3) will hang until there is a connection to accept.
