How to skip multiple lines when reading from a file pointer in PHP

Question

I have a somewhat irregularly structured CSV file I'm reading with fopen() and fgetcsv(). The first 5 lines are to be discarded.

Is there an efficient way to discard those 5 lines? What I have now is:

$fp = fopen($path,'r');
fgets($fp);fgets($fp);fgets($fp);fgets($fp);fgets($fp);

which gets the job done, but seems dirty.

With SPLFileObj you can do seek with line numbers. Without it you have to know the byte values — ArtisticPhoenix

Yes - Seek. with fseek you need the byte offset, which isn't workable. it's pretty trivial though. There is actually a trick with $File->seek(PHP_INT_MAX); $end = $File->key(); $File->rewind() that can give you the line total much faster then iterating through it.... :0} — ArtisticPhoenix

So like this

 $CSV = new SplFileObject($file);
 $CSV->seek(5);
 $row = $CSV->fgetcsv();

Only a hint: There is a difference between skip 5 text lines (request of the OP) and skip 5 table rows offered here. Maybe the OP wants this.
