gzseekSeek on a gz-file pointer Description
int gzseek
( resource
$zp
, int $offset
[, int $whence = SEEK_SET
] )Sets the file position indicator for the given file pointer to the given offset byte into the file stream. Equivalent to calling (in C) gzseek(zp, offset, SEEK_SET). If the file is opened for reading, this function is emulated but can be extremely slow. If the file is opened for writing, only forward seeks are supported; gzseek then compresses a sequence of zeroes up to the new starting position. Parameters
Return ValuesUpon success, returns 0; otherwise, returns -1. Note that seeking past EOF is not considered an error. Examples
