stream_set_read_buffer

(PHP 5 >= 5.3.3, PHP 7)

stream_set_read_bufferSet read file buffering on the given stream


说明

stream_set_read_buffer ( resource $stream , int $buffer ) : int

Sets the read buffer. It's the equivalent of stream_set_write_buffer(), but for read operations.


参数

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.


返回值

Returns 0 on success, or another value if the request cannot be honored.
