Are there any potential pitfalls or limitations when using heredoc syntax in PHP?

One potential limitation of using heredoc syntax in PHP is that it can be less readable when dealing with large blocks of text or complex formatting. To improve readability, consider using alternative methods such as concatenation or storing the text in a separate file and including it in your code.

// Example of using concatenation instead of heredoc syntax
$text = "This is a long piece of text that may be difficult to read with heredoc syntax. ";
$text .= "Instead, consider using concatenation to break it up into smaller, more manageable chunks.";
echo $text;
