How can the modulo operator be used to efficiently display data in rows of 2 entries in PHP?

To efficiently display data in rows of 2 entries in PHP, we can use the modulo operator (%) to determine when to start a new row. By checking if the current index is divisible by 2, we can insert a line break to create the desired 2-entry rows. 

$data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

foreach ($data as $index => $entry) {
    echo $entry;

    if (($index + 1) % 2 == 0) {
        echo "<br>";
    } else {
        echo " ";
    }
}
