streamWrapper::stream_eof — Tests for end-of-file on a file pointer
This method is called in response to feof() .
此函数没有参数。
Should return TRUE
if the read/write position is at the end of the stream and if no more data is available to be read, or FALSE
otherwise.
When reading the whole file (for example, with file_get_contents() ), PHP will call streamWrapper::stream_read() followed by streamWrapper::stream_eof() in a loop but as long as streamWrapper::stream_read() returns a non-empty string, the return value of streamWrapper::stream_eof() is ignored.
