PHP SQL Joomla存储表将两列放入数组并稍后回显它们

Question

So I have a simple table with two columns. The table is called "mytable" and the columns are "product" and "id". The table has about 12 entries.

            $db = JFactory::getDbo();
            $query = "SELECT * FROM mytable";
            $db->setQuery($query);
            $results = $db->loadObjectList();

So I've gotten this far querying successfully but I want to call back the results of each row. That's the part I am stuck on. I need to store this into an array so I can later make a while loop spitting out each row. Also I cannot echo it right underneath that code. This needs to be stored in an array that is then pulled from another page and then I spit out each row. Thanks!

Try this,

        $db = JFactory::getDbo();
        $query = "SELECT * FROM mytable";
        $db->setQuery($query);
        $results = $db->loadObjectList();
        echo '<pre/>'
        print_r($results);//the resulted array is already in this variable you can iterate it later with foreach loop.

for looping and printing

foreach($results as $key=>$value){
 echo 'Product-->'.$value->product;
 echo 'ID-->'.$value->id;
}

check the Joomla DB query for more details.

Hope it helps..
