How can CSS or JavaScript be used to create a tooltip effect in PHP for displaying additional data without shifting the rest of the content?

To create a tooltip effect in PHP for displaying additional data without shifting the rest of the content, you can use CSS and JavaScript to show and hide the tooltip when hovering over a specific element. By positioning the tooltip absolutely and setting its display property to none by default, you can ensure that it doesn't affect the layout of the rest of the content. 

<!DOCTYPE html>
<html>
<head>
  <style>
    .tooltip {
      position: relative;
      display: inline-block;
    }

    .tooltip .tooltiptext {
      visibility: hidden;
      width: 120px;
      background-color: #555;
      color: #fff;
      text-align: center;
      border-radius: 6px;
      padding: 5px;
      position: absolute;
      z-index: 1;
      bottom: 125%;
      left: 50%;
      margin-left: -60px;
    }

    .tooltip:hover .tooltiptext {
      visibility: visible;
    }
  </style>
</head>
<body>

<div class="tooltip">Hover over me
  <span class="tooltiptext">Additional data</span>
</div>

</body>
</html>
