What is the purpose of using curly braces to access characters in a string in PHP?

When accessing characters in a string in PHP, using curly braces allows you to access individual characters by their position within the string. This is particularly useful when dealing with strings that contain special characters or variables. By using curly braces, you can clearly indicate the position of the character you want to access within the string. 

$string = "Hello, World!";
$position = 7;
$character = $string{$position};
echo $character; // Output: W
