(PHP 3, PHP 4 >= 4.0.0)

rewind -- Rewind the position of a file pointer

Description

int rewind ( int fp)

Sets the file position indicator for fp to the beginning of the file stream.

If an error occurs, returns 0.

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

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

See also fseek() and ftell().

`rewind doesn't work if you are trying to write to a file that you have opened in a or a+ mode. The write always appends to the end of the file (unless you use ftruncate to set the file size to zero)`
