1.$hs = new HandlerSocket($host, $port);
2.while(true) {
   $hs->openIndex(2, $dbname, $table,HandlerSocket::PRIMARY,$filed)));
}
3.Run the top command to observe the memory footprint

What is the expected output? What do you see instead?
Stable memory footprint
Sustained increase in memory footprint

What version of the product are you using? On what operating system?
php-handelrsocket-0.3.1.tar.gz  centos or ubuntu

Please provide any additional information below.
The reason smart_str_appendl_ex(&request_field, Z_STRVAL_P(field), 
Z_STRLEN_P(field), 1) function to apply for the memory but did not release 
which in handlersocket.c 2247 line.
The solution is to add 2278 line smart_str_free_ex(request_field, 1); in the 
2277 line hs_request_string(&request, request_field.c, request_field.len);behind
