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.
handleThe file pointer must be valid, and must point to a file successfully opened by fopen().
Returns TRUE on success or FALSE on failure.
Example #1 rewind() overwriting example
<?php
$handle = fopen('output.txt', 'r+');
fwrite($handle, 'Really long sentence.');
rewind($handle);
fwrite($handle, 'Foo');

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