What are the advantages and disadvantages of using character indexing for data representation in PHP?

When using character indexing for data representation in PHP, the main advantage is that it allows for easy access and manipulation of individual characters within a string. However, this method can be less efficient when working with large strings or when needing to perform complex operations on the data. 

// Example of using character indexing for data representation in PHP
$string = "Hello World";

// Accessing individual characters using character indexing
echo $string[0]; // Output: H
echo $string[6]; // Output: W

// Manipulating individual characters
$string[0] = 'J';
echo $string; // Output: Jello World
