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><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>&lt;th&gt;Name&lt;/th&gt;&lt;th&gt;Email&lt;/th&gt;&lt;th&gt;Phone&lt;/th&gt;</pre><div class="contentsignin">Copy after login</div></div><p><strong>2. Table data (<code><td>):

Used to store the actual data in the table. It is usually centered and positioned below the header data.

Example:

<td>John Doe</td><td>john.doe@example.com</td><td>123-456-7890</td>

3. Table row (<tr>):

Used to define rows in a table. It organizes tabular data into horizontal rows.

Example:

<tr><th colspan="4">User Details</th></tr>

4. Table column group (<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>):

Used to provide a title or summary for the table. It usually appears above or below the table and uses the <caption> tag.

Example:

<caption>Customer Summary</caption>

6. Table border (<tbody>):

Used to define the form body. It contains most of the table's data, but not the title or titles.

Example:

<tbody>
  <tr><td>...</td><td>...</td><td>...</td></tr>
</tbody>

Practical case:

The following is a PHP example that demonstrates how to create and display using these elements Simple table:

 'John Doe', 'Email' => 'john.doe@example.com', 'Phone' => '123-456-7890'],
  ['Name' => 'Jane Smith', 'Email' => 'jane.smith@example.com', 'Phone' => '456-789-1230'],
];
?>






    <th>Name</th><th>Email</th><th>Phone</th>
  
  <tbody>
    
      <tr>
        

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.
