stream_set_read_buffer
(PHP 5 >= 5.3.3)
stream_set_read_buffer — Set read file buffering on the given stream
Description
   int stream_set_read_buffer
    ( resource $stream
   , int $buffer
   )
  Sets the read buffer. It's the equivalent of stream_set_write_buffer(), but for read operations.
Parameters
- stream
- 
     The file pointer. 
- buffer
- 
     The number of bytes to buffer. If buffer is 0 then read operations are unbuffered. This ensures that all reads with fread() are completed before other processes are allowed to write to that output stream. 
Return Values
Returns 0 on success, or EOF if the request cannot be honored.
