What are some potential pitfalls when using regular expressions for replacing content in PHP templates?

One potential pitfall when using regular expressions for replacing content in PHP templates is that the patterns may not match the content as expected, leading to unintended replacements or errors in the output. To avoid this, it is important to thoroughly test the regular expressions and ensure they are accurately targeting the desired content. 

// Example code snippet demonstrating how to use regular expressions for content replacement in PHP templates

$template = "<p>Hello, [name]!</p>";
$pattern = "/\[name\]/";
$replacement = "John";

$newTemplate = preg_replace($pattern, $replacement, $template);

echo $newTemplate;
