Re: [PHP] pharse file random work with -n lines

I'm not sure what is wrong, you should add print_r function in different places to see if the variables really contain what they should.

You don't need to use fgets after the while loop (you are at the end of
the file), $rand_array will contain your desired random rows:
<?php
$i = 0;
$fp = fopen ("../../../../../home/httpd/html/Classifieds/data/ads.data",
"r");
while($tmp= fgetcsv($fp,50000,"\|")) { $array[]=$tmp; }
fclose ($fp);
$rand_array=array_rand($array, 10);
foreach($rand_array as $line) { list ($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 ) = $line;
echo " <a
href=\"http://www.browseabit.com/cgi-bin/Classifieds/classifieds.cgi?session
_key=&search_and_display_db_button=on&db_id=$adnr&query=retrieval\"
target=\"_blanko\">$Endzwei $End3</a> ";
}
?>

Sorry, I forgot about the random part. Append the lines to an array, and
then use array_rand:
while($tmp= fgetcsv($fp,50000,"\|")) { $array[]=$tmp; }

$rand_array=array_rand($array, 10);

}

are you sure you want "\|" and not "|"?

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);
