if i give Limit for mysql query through php command line script like this for ex. $limit=500; $total_items = 1500; for($start=0;$start<$total_items;){ $command = "/usr/bin/php -q /home/sitename/public_html/admin/feedmanager/test.php feedid ".$_GET['feedid']." start ".$start." end ".$limit ; $start = $start+$limit; $command_result = system($command); } so it's execute command for 3 times so it give limit to sql query but if i have 27000 data so it takes long time? so my question is that is that any way from php command line script that i can use for collect all the data at once?
