Constantele de mai jos sunt definite de această extensie și vor fi disponibile doar dacă această extensie a fost compilată în interiorul PHP, sau a fost încărcată dinamic în timpul rulării.
| Constant | Description |
|---|---|
STREAM_FILTER_READ |
Used with stream_filter_append() and stream_filter_prepend() to indicate that the specified filter should only be applied when reading |
STREAM_FILTER_WRITE |
Used with stream_filter_append() and stream_filter_prepend() to indicate that the specified filter should only be applied when writing |
STREAM_FILTER_ALL |
This constant is equivalent to
STREAM_FILTER_READ | STREAM_FILTER_WRITE
|
PSFS_PASS_ON |
Return Code indicating that the
userspace filter returned buckets in $out.
|
PSFS_FEED_ME |
Return Code indicating that the
userspace filter did not return buckets in $out
(i.e. No data available).
|
PSFS_ERR_FATAL |
Return Code indicating that the userspace filter encountered an unrecoverable error (i.e. Invalid data received). |
PSFS_FLAG_NORMAL |
Regular read/write. |
PSFS_FLAG_FLUSH_INC |
An incremental flush. |
PSFS_FLAG_FLUSH_CLOSE |
Final flush prior to closing. |
STREAM_USE_PATH |
Flag indicating if the stream used the include path. |
STREAM_REPORT_ERRORS |
Flag indicating if the wrapper is responsible for raising errors using trigger_error() during opening of the stream. If this flag is not set, you should not raise any errors. |
STREAM_CLIENT_ASYNC_CONNECT |
Open client socket asynchronously. This option must be used
together with the STREAM_CLIENT_CONNECT flag.
Used with stream_socket_client().
|
STREAM_CLIENT_CONNECT |
Open client socket connection. Client sockets should always include this flag. Used with stream_socket_client(). |
STREAM_CLIENT_PERSISTENT |
Client socket opened with stream_socket_client() should remain persistent between page loads. |
STREAM_SERVER_BIND |
Tells a stream created with stream_socket_server() to bind to the specified target. Server sockets should always include this flag. |
STREAM_SERVER_LISTEN |
Tells a stream created with stream_socket_server()
and bound using the STREAM_SERVER_BIND flag to start
listening on the socket. Connection-orientated transports (such as TCP)
must use this flag, otherwise the server socket will not be enabled.
Using this flag for connect-less transports (such as UDP) is an error.
|
STREAM_NOTIFY_RESOLVE |
A remote address required for this stream has been resolved, or the resolution
failed. See severity for an indication of which happened.
|
STREAM_NOTIFY_CONNECT |
A connection with an external resource has been established. |
STREAM_NOTIFY_AUTH_REQUIRED |
Additional authorization is required to access the specified resource.
Typical issued with severity level of
STREAM_NOTIFY_SEVERITY_ERR.
|
STREAM_NOTIFY_MIME_TYPE_IS |
The mime-type of resource has been identified,
refer to message for a description of the
discovered type.
|
STREAM_NOTIFY_FILE_SIZE_IS |
The size of the resource has been discovered. |
STREAM_NOTIFY_REDIRECTED |
The external resource has redirected the stream to an alternate
location. Refer to message.
|
STREAM_NOTIFY_PROGRESS |
Indicates current progress of the stream transfer in
bytes_transferred and possibly
bytes_max as well.
|
STREAM_NOTIFY_COMPLETED |
There is no more data available on the stream. |
STREAM_NOTIFY_FAILURE |
A generic error occurred on the stream, consult
message and message_code
for details.
|
STREAM_NOTIFY_AUTH_RESULT |
Authorization has been completed (with or without success). |
STREAM_NOTIFY_SEVERITY_INFO |
Normal, non-error related, notification. |
STREAM_NOTIFY_SEVERITY_WARN |
Non critical error condition. Processing may continue. |
STREAM_NOTIFY_SEVERITY_ERR |
A critical error occurred. Processing cannot continue. |
STREAM_IPPROTO_ICMP + |
Provides a ICMP socket. |
STREAM_IPPROTO_IP + |
Provides a IP socket. |
STREAM_IPPROTO_RAW + |
Provides a RAW socket. |
STREAM_IPPROTO_TCP + |
Provides a TCP socket. |
STREAM_IPPROTO_UDP + |
Provides a UDP socket. |
STREAM_PF_INET + |
Internet Protocol Version 4 (IPv4). |
STREAM_PF_INET6 + |
Internet Protocol Version 6 (IPv6). |
STREAM_PF_UNIX + |
Unix system internal protocols. |
STREAM_SOCK_DGRAM + |
Provides datagrams, which are connectionless messages (UDP, for example). |
STREAM_SOCK_RAW + |
Provides a raw socket, which provides access to internal network protocols and interfaces. Usually this type of socket is just available to the root user. |
STREAM_SOCK_RDM + |
Provides a RDM (Reliably-delivered messages) socket. |
STREAM_SOCK_SEQPACKET + |
Provides a sequenced packet stream socket. |
STREAM_SOCK_STREAM + |
Provides sequenced, two-way byte streams with a transmission mechanism for out-of-band data (TCP, for example). |
STREAM_SHUT_RD |
Used with stream_socket_shutdown() to disable further receptions. Added in PHP 5.2.1. |
STREAM_SHUT_WR |
Used with stream_socket_shutdown() to disable further transmissions. Added in PHP 5.2.1. |
STREAM_SHUT_RDWR |
Used with stream_socket_shutdown() to disable further receptions and transmissions. Added in PHP 5.2.1. |
STREAM_CAST_FOR_SELECT |
Stream casting, for when stream_select() is calling stream_cast(). |
STREAM_CAST_AS_STREAM |
Stream casting, when stream_cast() is called otherwise (see above). |
STREAM_META_TOUCH |
