What are some best practices for PHP code review, especially when dealing with div problems?

When dealing with div problems in PHP code, it's important to ensure proper HTML structure and syntax to avoid layout issues. One common mistake is not properly closing div tags, which can lead to unexpected layout behavior. To address this, always make sure to close div tags in the correct order and validate your HTML code to catch any syntax errors.

<div class="container">
    <div class="row">
        <div class="col-md-6">
            <p>This is some content</p>
        </div>
        <div class="col-md-6">
            <p>This is some more content</p>
        </div>
    </div>
</div>
