Question

I am using PDO to get result from database and then using foreach loop to display data.

my code is

$result1=$objPage->getGallery($id);
foreach($result1 as $row)
{

    echo "pic1=" . $row['pic']; 
    echo "pic2=" . $row['pic']; 
    echo "pic3=" . $row['pic']; 
    echo "<br>";    
}

Actually, I want to display three pictures names in one line and then next 3 names.

But now its printing one name 3 times.

You can use an external flag, like this:

$flag = 0;
$result1=$objPage->getGallery($id);
foreach($result1 as $row) {
    echo "pic" . ($flag + 1) . "=" . $row['pic'];
    if( $flag % 3 == 0 )
        echo "<br>";
    $flag++;   
}
