What are the potential issues with using tables for layout in PHP web development?

Using tables for layout in PHP web development can lead to several issues, such as making the code harder to maintain, reducing flexibility in design changes, and affecting the responsiveness of the website. To solve this issue, it is recommended to use CSS for layout and positioning elements on the webpage.
