(PHP 5 >= 5.3.3, PHP 7)
Set read file buffering on the given stream
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 read from that input stream.
Returns:
Returns 0 on success, or another value if the request cannot be honored.
