The following is a list of the various URL style socket transports that PHP has built-in for use with the streams based socket functions such as fsockopen(), and stream_socket_client(). These transports do not apply to the Sockets Extension.
For a list of transports installed in your version of PHP use stream_get_transports().
PHP 3, PHP 4, PHP 5.
tls:// since PHP 4.3.0
sslv3:// since PHP 5.0.2
If no transport is specified,
tcp:// will be assumed.
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.
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
[fe80::1]. This is to
distinguish between the colons used in an IPv6 address and
the colon used to delimit the portnumber.
(available only when openssl support is compiled into PHP) are extensions
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.
sslv3:// will select the SSL V2 or SSL V3
Location of Certificate Authority file on local filesystem
which should be used with the |
|Path to local certificate file on filesystem. It must be a PEM encoded file which contains your certificate and private key. It can optionally contain the certificate chain of issuers.|
Passphrase with which your |
|Common Name we are expecting. PHP will perform limited wildcard matching. If the Common Name does not match this, the connection attempt will fail.|
