In the PHP programming language, outputting the last value of an array may be a common task. This usually happens when you need to display a list of entries with a specific total, such as the top 10 articles, and retrieve it from the database as an array. In this case, you may want to display only the last article in the list. In this article, we will discuss how to output the last value in an array in PHP.

1. Use the array_pop() function

The fastest and easiest way is to use the array_pop() function in PHP. This function pops and returns the last element of the array. Here is an example array:

$myArray = array('apple', 'banana', 'orange', 'grape');

We can use the following code to output the last element in the array:

echo array_pop($myArray);\

This will output "grape". Note that this function will also remove the last element from the original array. If you don't want to change the original array, you can assign it to a new variable before outputting it.

$lastVal = array_pop($myArray);
echo $lastVal;

2. Use the end() function

Another method is to use the end() function. Unlike the array_pop() function, this function does not remove elements from the original array. It moves the pointer to the last element of the array and returns the value of that element. Here is a sample code:

$myArray = array('apple', 'banana', 'orange', 'grape');
echo end($myArray);

This will output "grape". Note that this function only returns the value of the last element, not the array itself.

3. Use the count() function

You can also use the count() function to determine the index position of the last element in the array. You can then use that index to output the element. The following is a sample code:

$myArray = array('apple', 'banana', 'orange', 'grape');
$lastIndex = count($myArray) - 1;
echo $myArray[$lastIndex];

In this example, we first use the count() function to get the number of elements of the array, and then decrement it by 1 so that it becomes the index of the last element. Next, we use that index to get the value of the last element from the array.

Summary:

The above are three methods of outputting the last element in an array in PHP. These methods are very simple and easy to understand. You can choose one of them based on your specific needs and preferences. Whichever method you use, you can quickly and easily print the last element in an array.
