Essential knowledge for processing table data in PHP: Purpose of elements
Tables are a common method for processing data in Web development . PHP provides a rich set of functions for creating, manipulating, and querying tabular data. The following are the commonly used elements and their uses in PHP table processing:
1. Header data (<th>): <p>Used To define the table title. It provides structure to the table and is usually displayed in bold or larger font size. </p>
<p><strong>Example: </strong></p><pre class='brush:php;toolbar:false;'><th>Name</th><th>Email</th><th>Phone</th></pre><p><strong>2. Table data (<code><td>): <p> Used to store the actual data in the table. It is usually centered and positioned below the header data. </p>
<p><strong>Example: </strong></p><pre class='brush:php;toolbar:false;'><td>John Doe</td><td>john.doe@example.com</td><td>123-456-7890</td></pre><p><strong>3. Table row (<code><tr>): <p> Used to define rows in a table. It organizes tabular data into horizontal rows. </p>
<p><strong>Example: </strong></p><pre class='brush:php;toolbar:false;'><tr><th colspan="4">User Details</th></tr></pre><p><strong>4. Table column group (<code><colgroup></colgroup>
):
Used to group table columns together. It allows you to set style, alignment, or other properties for the selected columns.
Example:
<colgroup span="2"></colgroup> <!-- 将前两列分组 -->
5. Table title (<caption></caption>
):
Used to provide a title or summary for the table. It usually appears above or below the table and uses the <caption></caption>
tag.
Example:
<caption>Customer Summary</caption>
6. Table border (<tbody>): <p> Used to define the form body. It contains most of the table's data, but not the title or titles. </p>
<p><strong>Example:</strong></p><pre class='brush:php;toolbar:false;'><tbody>
<tr><td>...</td><td>...</td><td>...</td></tr>
</tbody></pre><p><strong>Practical case:</strong></p>
<p>The following is a PHP example that demonstrates how to create and display using these elements Simple table: </p><pre class='brush:php;toolbar:false;'><?php
$data = [
['Name' => 'John Doe', 'Email' => 'john.doe@example.com', 'Phone' => '123-456-7890'],
['Name' => 'Jane Smith', 'Email' => 'jane.smith@example.com', 'Phone' => '456-789-1230'],
];
?>
<!DOCTYPE html>
<html>
<body>
<table>
<thead>
<th>Name</th><th>Email</th><th>Phone</th>
</thead>
<tbody>
<?php foreach ($data as $row) : ?>
<tr>
<td><?php echo $row['Name']; ?></td>
<td><?php echo $row['Email']; ?></td>
<td><?php echo $row['Phone']; ?></td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
</body>
</html></pre><p>This example populates a table with data from an array. It uses table headers, table rows, and table elements to define table structure and content. </p>
