How can the layout be adjusted to ensure floated div containers display correctly in PHP output loops?

When using floated div containers in PHP output loops, it's important to clear the floats to ensure they display correctly. One way to do this is by using a clearfix class on a parent container to clear the floats. This will prevent any layout issues that may arise from floating elements within the loop.

echo '<div class="parent-container">';
while ($row = mysqli_fetch_assoc($result)) {
    echo '<div class="child-container">';
    // Output content here
    echo '</div>';
}
echo '</div>';
```

CSS:
```css
.parent-container:after {
    content: "";
    display: table;
    clear: both;
}
.child-container {
    float: left;
    /* Additional styling for child containers */
}
