rewind

(PHP 4, PHP 5)

rewind — Riavvolge la posizione di un puntatore a file

Descrizione

bool rewind ( resource $handle )

Pone l'indicatore alla posizione del file per handle all'inizio del flusso del file.

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

Il puntatore al file deve essere valido e deve puntare ad un file aperto con successo da fopen().

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.

Note that rewind($fd) is exactly the same as fseek($fd, 0, SEEK_SET)



rewind() just moves the location inside the file to the beginning, nothing more. Check if your stream is "seekable" before planning to use fseek/rewind.

As with fseek(), the rewind() function may not be used on file pointers returned by fopen() if they use the "http://" or "ftp://" formats.
