In PHP, how do I index strings for beginners?

In PHP, you can index strings using a variety of methods. The most common approach is to access characters in a string using their index. PHP uses zero-based indexing, meaning the first character of a string is at index 0.

        <?php
            $string = "Hello, World!";
            // Accessing the first character
            $firstCharacter = $string[0]; // 'H'
            // Accessing the fifth character
            $fifthCharacter = $string[4]; // 'o'
            // Output the characters
            echo "The first character is: " . $firstCharacter . "<br>";
            echo "The fifth character is: " . $fifthCharacter;
        ?>
