What are the potential pitfalls of using str_replace() to format text output in PHP scripts?

Using str_replace() to format text output in PHP scripts can be problematic because it replaces all occurrences of a substring, which may lead to unintended replacements. To avoid this issue, it's better to use a combination of regular expressions and the preg_replace() function, which allows for more precise and flexible text manipulation. 

// Example of using preg_replace() for more precise text formatting
$text = "Hello, my name is John. I like programming in PHP.";
$formatted_text = preg_replace('/\b([A-Z][a-z]+)\b/', '<strong>$1</strong>', $text);
echo $formatted_text;
