What is a common method in PHP to generate a random word with 8 characters, including letters and numbers?

To generate a random word with 8 characters, including letters and numbers, in PHP, you can create a function that generates a random string by combining letters and numbers. You can use the `str_shuffle` function to shuffle the characters and then take the first 8 characters to form the random word.

function generateRandomWord($length = 8) {
    $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $randomString = '';
    
    for ($i = 0; $i < $length; $i++) {
        $randomString .= $characters[rand(0, strlen($characters) - 1)];
    }
    
    return $randomString;
}

$randomWord = generateRandomWord();
echo $randomWord;
