What is the potential cause of a syntax error in PHP when trying to insert an HTML link with an {if} statement?

When trying to insert an HTML link within an {if} statement in PHP, a common cause of a syntax error is improper mixing of PHP and HTML code. To solve this issue, you can use PHP's alternative syntax for control structures, such as using "endif;" instead of closing curly braces. This helps to clearly separate PHP logic from HTML markup within the {if} statement.

<?php
$condition = true;
?>

<?php if ($condition): ?>
    <a href="#">Link</a>
<?php endif; ?>
