getMetadata(?string $key = null)
Get stream metadata as an associative array or retrieve a specific key.
Get stream metadata as an associative array or retrieve a specific key.
The keys returned are identical to the keys returned from PHP's
stream_get_meta_data() function.
Parameters

Specific metadata to retrieve.
|
Returns
Returns an associative array if no key is
provided. Returns a specific key value if a key is provided and the
value is found, or null if the key is not found.

__toString(): string
Reads all data from the stream into a string, from the beginning to end.
Reads all data from the stream into a string, from the beginning to end.
This method MUST attempt to seek to the beginning of the stream before
reading data and read the stream until the end is reached.
Warning: This could attempt to load a large amount of data into memory.
This method MUST NOT raise an exception in order to conform with PHP's
string casting operations.

If the stream is not seekable, this method will raise an exception;
otherwise, it will perform a seek(0).

public
|
read(int $length): string
Read data from the stream.
Read data from the stream.
Parameters
| $length |
Read up to $length bytes from the object and return
them. Fewer than $length bytes may be returned if underlying stream
call returns fewer bytes.
|
Returns
Returns the data read from the stream, or an empty string
if no bytes are available.

write(string $string): int
Write data to the stream.
Write data to the stream.
Parameters
| $string |
The string that is to be written.
|
Returns
Returns the number of bytes written to the stream.
Implements

seek(int $offset, SEEK_SET|SEEK_CUR|SEEK_END $whence = SEEK_SET): void
Seek to a position in the stream.
Seek to a position in the stream.
Parameters
| $offset |
Stream offset
|
| $whence |
Specifies how the cursor position will be calculated
based on the seek offset. Valid values are identical to the built-in
PHP $whence values for fseek(). SEEK_SET: Set position equal to
offset bytes SEEK_CUR: Set position to current location plus offset
SEEK_END: Set position to end-of-stream plus offset.
