streamWrapper::stream_read
(PHP 4 >= 4.3.2, PHP 5)
streamWrapper::stream_read — Read from stream
Description
This method is called in response to fread() and fgets().
Note:
Remember to update the read/write position of the stream (by the number of bytes that were successfully read).
Parameters
- count
-
How many bytes of data from the current position should be returned.
Return Values
If there are less than count bytes available, return as many as are available. If no more data is available, return either FALSE or an empty string.
Errors/Exceptions
Emits E_WARNING if call to this method fails (i.e. not implemented).
Note:
If the return value is longer then count an E_WARNING error will be emitted, and excess data will be lost.
Notes
Note:
streamWrapper::stream_eof() is called directly after calling streamWrapper::stream_read() to check if EOF has been reached. If not implemented, EOF is assumed.
