In PHP, adding horizontal lines to a table can be achieved by adding CSS styles.

CSS (Cascading Style Sheets) is a language used to control the style and layout of web pages and can add styles to HTML elements. By adding specific CSS styles, the table element can be displayed as a table with horizontal lines on the web page.

The following are the steps to add horizontal lines to a table:

Step 1: Create an HTML table element

First, create a table element in HTML. You can use the table tag and Other related tags to achieve.

The following is a simple HTML table example:

<table>
  <tr>
    <th>姓名</th>
    <th>性别</th>
    <th>年龄</th>
  </tr>
  <tr>
    <td>张三</td>
    <td>男</td>
    <td>28</td>
  </tr>
  <tr>
    <td>李四</td>
    <td>女</td>
    <td>32</td>
  </tr>
</table>

In the above code, a simple data table is created through the table element, containing three columns: name, gender and age, and two data row.

Step 2: Add CSS style

Next, add CSS style in PHP to add horizontal lines to the table.

The following is an example of using CSS styles to add horizontal lines to a table:

<style type="text/css">
table {
  border-collapse: collapse;
  width: 100%;
}

table th, table td {
  border: 1px solid #ccc;
}

table th {
  background-color: #f7f7f7;
  font-weight: bold;
}

table tr:nth-child(even) {
  background-color: #f2f2f2;
}

table tr:hover {
  background-color: #eaeaea;
}
</style>

Copy after login

In the above code, a table style is defined and the table border and width are set. At the same time, the border style of the table header and content cells, as well as the background color and bold effect of the table header are defined. By setting the background color of even-numbered rows and mouse hover, the effect of a table with horizontal lines is achieved.

Step 3: Apply CSS styles to HTML table elements

Finally, apply the above CSS styles to HTML table elements.

The following is a complete PHP code example:

<!DOCTYPE html>
<html>
<head>
  <title>PHP Table Style</title>
  <meta charset="UTF-8">
  <style type="text/css">
    table {
      border-collapse: collapse;
      width: 100%;
    }

    table th, table td {
      border: 1px solid #ccc;
    }

    table th {
      background-color: #f7f7f7;
      font-weight: bold;
    }

    table tr:nth-child(even) {
      background-color: #f2f2f2;
    }

    table tr:hover {
      background-color: #eaeaea;
    }
  </style>
</head>
<body>
  <table>
    <tr>
      <th>姓名</th>
      <th>性别</th>
      <th>年龄</th>
    </tr>
    <tr>
      <td>张三</td>
      <td>男</td>
      <td>28</td>
    </tr>
    <tr>
      <td>李四</td>
      <td>女</td>
      <td>32</td>
    </tr>
  </table>
</body>
</html>

By running the above PHP code, a data table with horizontal lines can be displayed on the web page.
