What is the issue with the loop and multidimensional array in the PHP script?

The issue with the loop and multidimensional array in the PHP script is that the loop is not correctly iterating over the elements of the multidimensional array. To solve this issue, we need to use nested loops to iterate over both dimensions of the array. 

// Incorrect loop over a multidimensional array
$multiArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

foreach ($multiArray as $row) {
    foreach ($row as $value) {
        echo $value . " ";
    }
}

// Correct loop over a multidimensional array
$multiArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

foreach ($multiArray as $row) {
    foreach ($row as $value) {
        echo $value . " ";
    }
}
