Detailed introduction to setting the background of PHP tables

When writing a PHP program to output a table, setting the table background is a very basic skill. This article will introduce in detail how to set the PHP table background.

In HTML, you can use the

tag to create a table. We can control the background style of the table by setting the attributes of the tag. In PHP, you can use the echo function to output HTML code to create a table, and set the background style of the table while outputting the table.

The specific implementation method is as follows:

1. Use CSS styles to set the table background

In HTML, you can use CSS styles to set the background color or background for the table picture. In PHP, you can use the echo function to output HTML code with style attributes to set the background style of a table.

For example, the following code creates a table with a red background:

<?php echo "<table style=&#39;background-color: red&#39;>";
echo "<tr>
<th>姓名</th>
<th>年龄</th>
</tr>";
echo "<tr>
<td>张三</td>
<td>18</td>
</tr>";
echo "<tr>
<td>李四</td>
<td>20</td>
</tr>";
echo "

"; ?>

The table output by the above code is as follows:

Similarly, You can use the background-image attribute to set a background image for the table, for example:

<?php echo "<table style=&#39;background-image: url(bg.jpg)&#39;>";
echo "<tr>
<th>姓名</th>
<th>年龄</th>
</tr>";
echo "<tr>
<td>张三</td>
<td>18</td>
</tr>";
echo "<tr>
<td>李四</td>
<td>20</td>
</tr>";
echo "

"; ?>

The table output by the above code is as follows:

2. Use HTML color codes Set the table background

There are some color codes in HTML that can be used to set the background style of the table, for example:

• ffffff: white

• 000000：Black

• ff0000：Red

• 00ff00：Green

• 0000ff: Blue

You can use the echo function in PHP to output HTML code with the bgcolor attribute to set the background color of the table. For example, the following code creates a table with a white background:

<?php echo "<table bgcolor=&#39;#ffffff&#39;>";
echo "<tr>
<th>姓名</th>
<th>年龄</th>
</tr>";
echo "<tr>
<td>张三</td>
<td>18</td>
</tr>";
echo "<tr>
<td>李四</td>
<td>20</td>
</tr>";
echo "";
?>

The table output by the above code is as follows:

3. Use CSS classes to set the table background

In HTML, you can use CSS classes to set the same style for multiple elements. Similarly, in PHP, you can use the echo function to output HTML code with a class attribute to set the same background style for multiple tables.

For example, the following code creates two tables and sets their background styles using the same CSS class:

<?php echo "<style>.bg { background-color: #eeeeee; }";
echo "

"; echo ""; echo ""; echo ""; echo "

姓名	年龄
张三	18
李四	20

"; echo ""; echo ""; echo ""; echo ""; echo "

姓名	年龄
王五	22
赵六	24

"; ?>

The table output by the above code is as follows:

Summary

PHP table background settings can be implemented using CSS styles, HTML color codes, and CSS classes. Use PHP to output HTML code with style attributes to set the table background. It should be noted that when using a CSS class to set the table background, the style of the CSS class needs to be defined in PHP first.
