# feof

(PHP 3, PHP 4 , PHP 5)

feof -- Tests for end-of-file on a file pointer

## Description

bool feof ( resource handle)

Returns `TRUE` if the file pointer is at EOF or an error occurs (including socket timeout); otherwise returns `FALSE`.

切記!
feof() will return `TRUE` only if the connection opened by fsockopen() is closed. This can cause a script to timeout. The workaround for this is to use stream_set_timeout(), so that feof() will return `FALSE` on timeout.

The file pointer must be valid, and must point to a file successfully opened by fopen() or fsockopen().
