PHP 操作socket 实现简易聊天室

<?php
$socket =  socket_create(AF_INET, SOCK_STREAM, SOL_TCP );
socket_bind($socket ,\'127.0.0.1\', 11211 );
socket_listen( $socket ,5);
while( true ){
    $con = socket_accept( $socket );
    if( $con !==false ){
        socket_write($con, \'init\', 4 );
        while(  $str = socket_read( $con,1024 ) ){
            echo \'client:\'.$str."\n";
            $ret = fgets(STDIN);
        }
        socket_close( $con );
    }
}
