What are the best practices for defining table headers and table cells in PHP?

When defining table headers and table cells in PHP, it is important to use the <th> tag for table headers and the <td> tag for table cells. This helps to properly structure the table and make it more accessible for screen readers and other assistive technologies. Additionally, using semantic markup like <thead>, <tbody>, and <tfoot> can further enhance the organization of the table.

&lt;table&gt;
  &lt;thead&gt;
    &lt;tr&gt;
      &lt;th&gt;Name&lt;/th&gt;
      &lt;th&gt;Age&lt;/th&gt;
      &lt;th&gt;Location&lt;/th&gt;
    &lt;/tr&gt;
  &lt;/thead&gt;
  &lt;tbody&gt;
    &lt;tr&gt;
      &lt;td&gt;John Doe&lt;/td&gt;
      &lt;td&gt;30&lt;/td&gt;
      &lt;td&gt;New York&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
      &lt;td&gt;Jane Smith&lt;/td&gt;
      &lt;td&gt;25&lt;/td&gt;
      &lt;td&gt;Los Angeles&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/tbody&gt;
&lt;/table&gt;
