Are there any best practices for handling text replacement with regular expressions in PHP?

When handling text replacement with regular expressions in PHP, it is important to use the `preg_replace()` function to perform the replacement. This function allows for pattern matching and substitution within a string using regular expressions. It is also recommended to escape any special characters in the pattern and replacement strings to avoid unexpected behavior. 

$text = "Hello, World!";
$pattern = "/Hello/";
$replacement = "Hi";
$replaced_text = preg_replace($pattern, $replacement, $text);
echo $replaced_text; // Output: Hi, World!
