INDI DATA STREAM

persistent is a flag the controls whether the stream is opened as a persistent stream. Generally speaking, this parameter will usually be 0.

注意 If you need to seek and write to the stream, it does not make sense to use this function, because the stream it returns is not guaranteed to be bound to the same resource as the original stream.

The is particularly useful when accessing HTTP URLs where the start of the actual stream data is found after an indeterminate offset into the stream.

Returns an array of options on the specified stream or context.

Creates and returns a stream context with any parameters supplied in params preset.

Sets the timeout value on stream, expressed in the sum of seconds and microseconds.

Open text file for reading. The stream is positioned at the beginning of the file.

Returns an indexed array containing the name of all stream filters available on the running system.

Returns an indexed array containing the name of all stream wrappers available on the running system.

Open text file for reading and writing. The stream is positioned at the beginning of the file.

注意 Be aware that some stream implementations need to be handled very carefully. A few basic rules

注意 Although this function will not perform the conversion, some internal stream state might be changed by this call.

Truncate the file to zero length or create text file for writing. The stream is positioned at the beginning of the file.

Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file.

Since this option disables buffering at the streams API level, you may experience lower performance when using streams functions on the stream this is deemed acceptable because you have told streams that you will be using the functions to match the underlying stream implementation. Only use this option when you are sure you need it.

The internal position of the stream is advanced by the number of bytes that were read, so that subsequent reads will continue reading from that point.

Open text file for reading and writing. The file is created if it does not exist, otherwise it is truncated. The stream is positioned at the beginning of the file.

注意 NEVER call this function with an origstream that is reference by a file pointer in a PHP script! This function may cause the underlying stream to be closed which could cause a crash when the script next accesses the file pointer!

If not NULL, timeout specifies a maximum time to allow for the connection to be made. If the connection attempt takes longer than the timeout value, the connection attempt is aborted and NULL is returned to indicate that the stream could not be opened.

The 'b' character is ignored on all POSIX conforming systems which treat binary and text files in the same way. It is a good idea to specify the 'b' character whenever your stream is accessing data where the full 8 bits are important, so that your code will work when compiled on a system where the 'b' flag is important.
