Is it recommended to use PHP for controlling frames in a web development project?

Using PHP to control frames in a web development project is not recommended as frames are considered outdated and not recommended for modern web development practices. Instead, it is recommended to use more modern techniques like CSS Grid or Flexbox for layout control.
