Why is it important to avoid using PHP tags within PHP tags?

Using PHP tags within PHP tags can lead to syntax errors or unexpected behavior in your code. It is important to avoid nesting PHP tags to maintain clean and readable code. To solve this issue, you can simply concatenate strings or variables within a single set of PHP tags instead of opening and closing tags multiple times. 

// Incorrect way of nesting PHP tags
<?php
    echo "Hello";
    <?php echo "World"; ?>
?>

// Correct way of concatenating within a single set of PHP tags
<?php
    echo "Hello";
    echo "World";
?>
