What is the significance of using the e-modifier in the preg_replace function in PHP?

When using the e-modifier in the preg_replace function in PHP, it allows you to evaluate the replacement string as PHP code. This can be useful when you need to perform more complex replacements that involve logic or functions within the replacement string. Example: 

$text = "Hello, {name}!";
$name = "John";
$result = preg_replace('/\{name\}/e', '$name', $text);
echo $result; // Output: Hello, John!
