What are the implications of including whitespace before PHP code in HTML attributes when generating dynamic content?

Including whitespace before PHP code in HTML attributes can lead to unexpected output or errors in the generated content. To avoid this issue, it is important to ensure that there is no whitespace before the PHP code in HTML attributes. One way to solve this problem is to use PHP's `trim()` function to remove any leading or trailing whitespace from the PHP code before it is inserted into the HTML attribute. 

<?php
// Example of using trim() to remove whitespace before PHP code in HTML attributes
$name = "John Doe";
?>
<input type="text" value="<?php echo trim($name); ?>">
