The function fgetcsv() returns an array.

I am reading a csv file into an array. The csv file.

$csvfilename = users.csv;

fgetcsv($handle, 1000, ,)) !== FALSE) {
$arrUsers[]

fclose($handle);

When I echo out the elements in the elements in the array $arrUsers I get:
Array
Array
Array
foreach ($arrUsers as $user){
echo $user . br /;
}
I can't figure out why the word Array is replacing the actual data.

Try print_r($arrUsers);
also, the $line is an array of the CSV, so you're storing an array,
within the array $arrUsers.
foreach ($arrUsers as $user){
foreach ($user as $val) {
echo $val . br /;
}
echo 'hr /';
}

hi,
try to use print_r or var_dump to echo compound data type

You are echoing out an array. If you use something like print_r() or var_dump()
you will see the array elements
Thanks,

I'm new to this email list . . .
But is it customary to answer a question after it's already been adequately
answered?
Not trying to step on any toes. I just think if I were asking the question,
it would be unpleasant to continue receiving answers, especially the same
answer, after receiving one that is prompt, accurate, precise, concise, and
adequate.
Likewise, if I had answered the question -- promptly, accurately, precisely,
concisely, adequately -- I would find it equally, if not more, unpleasant to
see my answer displaced, or

I also will use Cron jobs every 15 minutes to collect the data. the question is: Is there a clever way to collect all those feed items without exhausting the server any Ideas I designed a job queuing system a while back when I had a similar problem. You can read about it here: http://stut.net/2009/05/29/php-job-queue/. Set that type of system up and add a job for each feed, set to run every 15 minutes. You can then watch the server and tune the number of concurrent job processors so you get the optimum balance between load and speed. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
