(PHP 4, PHP 5, PHP 7)
fseek — Seeks on a file pointer
Description
int fseek ( resource $handle , int $offset [, int $whence = SEEK_SET ] )
Sets the file position indicator for the file referenced by handle
. The new position, measured in bytes from the beginning of the file, is obtained by adding offset
to the position specified by whence
.
In general, it is allowed to seek past the end-of-file; if data is then written, reads in any unwritten region between the end-of-file and the sought position will yield bytes
