# rewind

(PHP 4, PHP 5)

rewind — Rewind the position of a file pointer

### 설명

bool rewind ( resource `$handle` )

Sets the file position indicator for `handle` to the beginning of the file stream.

> Note: If you have opened the file in append ("a" or "a+") mode, any data you write to the file will always be appended, regardless of the file position.

### 인수

`handle`

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

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

### 예제

Example #1 rewind() overwriting example

`<?php
$handle = fopen('output.txt', 'r+');
fwrite($handle, 'Really long sentence.');
rewind($handle);
fwrite($handle, 'Foo');
rewind($handle);
echo fread($handle, filesize('output.txt'));
fclose($handle);
?>`

위 예제의 출력 예시:

    Foolly long sentence.
