What are the advantages and disadvantages of using preg_replace callbacks in PHP?

When using preg_replace callbacks in PHP, one advantage is the ability to perform more complex replacements based on the matched pattern. This can be useful when you need to dynamically generate replacement strings. However, a disadvantage is that using callbacks can make the code harder to read and maintain compared to simple string replacements. 

// Example of using preg_replace callback in PHP
$text = "Hello, my name is [NAME].";
$replaced_text = preg_replace_callback('/\[NAME\]/', function($matches) {
    return "John Doe";
}, $text);

echo $replaced_text;
