What is the maximum number of TCP ports that can be consumed at any one time? How can I determine what the number is or increase it?

socket_getpeername
SOCKET_GETPEERNAME(3) 1 SOCKET_GETPEERNAME(3)socket_getpeername - Queries the remote side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on
its typeSYNOPSIS
bool socket_getpeername (resource $socket, string &$address, [int &$port])
DESCRIPTION
Queries the remote side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on its type.
PARAMETERS
o $socket
- A valid socket resource created with socket_create(3) or socket_accept(3).
o $address
- If the given socket is of type AF_INET or AF_INET6, socket_getpeername(3) will return the peers (remote) IP address in appropri-
ate notation (e.g. 127.0.0.1 or fe80::1) in the $address parameter and, if the optional $port parameter is present, also the
associated port. If the given socket is of type AF_UNIX, socket_getpeername(3) will return the Unix filesystem path (e.g.
/var/run/daemon.sock) in the $address parameter.
o $port
- If given, this will hold the port associated to $address.
RETURN VALUES
Returns TRUE on success or FALSE on failure. socket_getpeername(3) may also return FALSE if the socket type is not any of AF_INET,
AF_INET6, or AF_UNIX, in which case the last socket error code is not updated.
NOTES
Note
socket_getpeername(3) should not be used with AF_UNIX sockets created with socket_accept(3). Only sockets created with socket_con-
nect(3) or a primary server socket following a call to socket_bind(3) will return meaningful values.
Note
For having socket_getpeername(3) to return a meaningful value, the socket it is applied upon must of course be one for which the
concept of "peer" makes sense.
