(PHP 4, PHP 5, PHP 7)

Rewind the position of a file pointer

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.

Parameters:

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

Returns:

Returns TRUE on success or FALSE on failure.

Examples:

<?php
$handle = fopen('output.txt', 'r+');
 
fwrite($handle, 'Really long sentence.');

echo fread($handle, filesize('output.txt'));
 
fclose($handle);
