How can one effectively work with constants and variables in PHP arrays to avoid confusion or errors?

When working with constants and variables in PHP arrays, it's important to clearly differentiate between the two to avoid confusion and errors. One way to do this is by using constants for fixed values that won't change and variables for values that may change during the script execution. This helps maintain clarity and makes the code easier to read and debug. 

// Define a constant
define('MAX_SIZE', 100);

// Define a variable
$size = 50;

// Create an array using the constant and variable
$array = [
    'max_size' => MAX_SIZE,
    'current_size' => $size
];

// Access the values in the array
echo 'Max size: ' . $array['max_size'] . '<br>';
echo 'Current size: ' . $array['current_size'];
