SplFileObject::fseek — Seek to a position
Seek to a position in the file measured in bytes from the beginning of the file, obtained by adding offset to the position specified by whence.
The offset. A negative value can be used to move backwards through the file which is useful when SEEK_END is used as the whence value.
whence values are:
- SEEK_SET - Set position equal to offset bytes.
- SEEK_CUR - Set position to current location plus offset.
- SEEK_END - Set position to end-of-file plus offset.
If whence is not specified, it is assumed to be SEEK_SET.
Returns 0 if the seek was successful, -1 otherwise. Note that seeking past EOF is not considered an error.
Example #1 SplFileObject::fseek example
$file = new SplFileInfo("somefile.txt");
// Read first line
$data = $file->fgets();
// Move back to the beginning of the file
// Same as $file->rewind();
- fseek() - Seeks on a file pointer
