Summary: Set read file buffering on the given stream
PHP 5 >= 5.3.3Related methods: stream_set_write_buffer
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.
Returns 0 on success, or another value if the request cannot be honored.
- resource $stream: The file pointer.
- int $buffer: The number of bytes to buffer. If
bufferis 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.
