How to do multiple eregi on a file

I want to go through a file and pick out different peices of data, so a title then the associated link. However, I do not want to have to close and reopen the file. Is there a way to reset the $file pointer fo it points back to the beginning again?

Thanks

rewind($fd)

rewind() resets a file pointer identified by the $fd argument which is the return value of the fopen() call. The file pointer is positioned at the beginning of the file. See also ftell() and fseek().
This is from PHP docs. Good luck!
