[PHP] pharse file random work with -n lines

[WebDev]

 
how can you return this randomized? 
 
how can I get every time I call this function a random set of lines ?


Working Code to read 10 first lines and split the individual line into info careeners 
and do something with it ....
....


$i = 0;
$fp = fopen ("../../../../../public/httpd/html/datacontainer/data/storage.data", "r");
while (!feof ($fp) && $i < 10) {
$i++;
    $buffer = fgets($fp, 4096);
    list ($adnr, $user, $date, $listed, $hlong, $eins, $zwei, $drei, $vier, $usern, 
$locst, $locstaa, $locc, $funf, $sech, $email, $Url, $ClassCat, $ClassCat2, 
$Headstart, $Headend, $Descrip, $End1, $Endzwei, $End3, $Endvier, $Endfunf, $Endsech, 
$Endsieben, $Endacht, $Endne, $dreizwei, $dreidrei, $dreivier, $dreifunf, $dreisechs ) 
= split ("\|", $buffer);
    
\\ do something
}
fclose ($fp);
