  • List of Supported Socket
    Transports
  • Internet Domain: TCP, UDP, SSL, and TLS

  • Internet Domain: TCP, UDP, SSL, and TLS
  • Internet Domain: TCP, UDP, SSL, and TLS

    Internet Domain: TCP, UDP, SSL, and TLS

    PHP 4, PHP 5. ssl:// &
    tls:// since PHP 4.3.0 sslv2:// &
    sslv3:// since PHP 5.0.2

    Note: If no
    transport is specified, tcp:// will be assumed.

    • 127.0.0.1
    • fe80::1
    • www.example.com
    • tcp://127.0.0.1
    • tcp://fe80::1
    • tcp://www.example.com
    • udp://www.example.com
    • ssl://www.example.com
    • sslv2://www.example.com
    • sslv3://www.example.com
    • tls://www.example.com

    Internet Domain sockets expect a port number in
    addition to a target address. In the case of fsockopen() this is specified in a second
    parameter and therefore does not impact the formatting of transport
    URL. With stream_socket_client() and related functions
    as with traditional URLs however, the port number is specified as a
    suffix of the transport URL delimited by a colon.

    • tcp://127.0.0.1:80
    • tcp://[fe80::1]:80
    • tcp://www.example.com:80

    Note: IPv6 numeric
    addresses with port numbers

    In the second example above, while the IPv4
    and hostname examples are left untouched apart from the addition of
    their colon and portnumber, the IPv6 address is wrapped in square
    brackets: [fe80::1]. This is to distinguish between the
    colons used in an IPv6 address and the colon used to delimit the
    portnumber.

    The ssl:// and tls://
    transports (available only when openssl support is compiled into
    PHP) are extensions of the tcp:// transport which include
    SSL encryption. Since PHP 4.3.0 OpenSSL support must be statically
    compiled into PHP, since PHP 5.0.0 it may be compiled as a module
    or statically.

    ssl:// will attempt to negotiate an SSL
    V2, or SSL V3 connection depending on the capabilities and
    preferences of the remote host. sslv2:// and
    sslv3:// will select the SSL V2 or SSL V3 protocol
    explicitly.
