PHP标签嵌套在If语句中？

Question

The code problem:

<?php 
      if(strtolower($item["category"]) == "books" ) {
        ?>
        <tr>
          <th>Category</th>
          <td><?php echo $item["category"] ?></td>
        </tr>
 <?php } ?>

Why I have to write it like that? Instead of:

<?php
    if() {
     Do some things!
    }
?>

Answer 1

You can write PHP in HTML but you cant write HTML IN PHP(without using echo).

AFTER THIS

  <?php 
  if(strtolower($item["category"]) == "books" ) {
    ?>

You close the php tag to add html.

Then you open the php tag to put the closing braces for if and then close it back so that you can add html
