  Adding items to an array in PHP when working with digital currencies can be done using different methods. One commonly used method is the array_push() function, which allows you to add one or more elements to the end of an array. For example, you can use the following code snippet to add a new currency to an array: $currencyArray = array('Bitcoin', 'Ethereum'); array_push($currencyArray, 'Litecoin'); This will add 'Litecoin' to the end of the $currencyArray. Another method is to directly assign a value to a specific index in the array using the [] syntax. For example, you can use the following code to add a new currency at a specific index: $currencyArray[2] = 'Ripple'; This will add 'Ripple' at index 2 in the $currencyArray. It's important to ensure that the array is properly initialized before adding items to it to avoid any errors.
