streamWrapper::stream_eof

(PHP 4 >= 4.3.2, PHP 5, PHP 7)

streamWrapper::stream_eof — Tests for end-of-file on a file pointer

说明

public streamWrapper::stream_eof ( void ) : bool

This method is called in response to feof().

参数

此函数没有参数。

返回值

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.

注释

Warning

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.
