PHP/4.3.9 contrary to the notes, gzseek() returns -1 if I try to seek past the end of the file. here is a function that will return the last seekable position, and put the file pointer there. /** sets the file pointer at the end of the file * and returns the number of bytes in the file. */ function gzend($fh) { $d = 1<<14; $eof = $d; while ( gzseek($fh, $eof) == 0 ) $eof += $d; while ( $d > 1 ) { $d >>= 1; $eof += $d * (gzseek($fh, $eof)? -1 : 1); } return $eof; }
