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. WebDev wrote:

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,

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); WebDev wrote:
