    Descrição

    socket_getpeername(Socket$socket, string&$address, int&$port = null): bool

    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.

    Parâmetros

    socket

    A Socket instance created with socket_create() or socket_accept().

    address

    If the given socket is of type AF_INET or AF_INET6, socket_getpeername() will return the peers (remote) IP address in appropriate 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() will return the Unix filesystem path (e.g. /var/run/daemon.sock) in the address parameter.

    port

    If given, this will hold the port associated to address.

    Valor Retornado

    Retorna true em caso de sucesso ou false em caso de falha. socket_getpeername() 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.

    8.0.0 O parâmetro socket agora espera uma instância de Socket; anteriormente, um resource era esperado.

    Notas

    Nota:

    socket_getpeername() should not be used with AF_UNIX sockets created with socket_accept(). Only sockets created with socket_connect() or a primary server socket following a call to socket_bind() will return meaningful values.

    Nota:

    For having socket_getpeername() to return a meaningful value, the socket it is applied upon must of course be one for which the concept of "peer" makes sense.
