Question

PHP exec() . can i use this to export data to csv with a search criteria.

As the result is huge can i use exec and run system command as a parameter and return a result as csv or zip.

Is this possible??

Sure you can. Here is a sample code we use to do daily MyQSL backup:

while ($obj = mysql_fetch_object($res)) {
        $file = $path.$obj->base.".sql";
        $cmd = "rm -f ".$file;
        exec($cmd);
        $cmd = "nice -19 mysqldump -h".$host." -u".$login." -p".$pass." ".$obj->base." > ".$file;
        exec($cmd);
        $sql = "update save_mysql set last_daily=NOW() where base = '".$obj->base."'";
        mysql_query($sql);
}
