How to Retrieve the Last Element of an Array in PHP Without Deleting It?

Retrieving the Last Array Element Without Deletion

Arrays in programming languages provide a convenient method of storing and managing data. However, accessing the last element of an array can be tricky without inadvertently deleting it.

Traditionally, array_pop() has been used to retrieve the last element while also removing it from the array. To circumvent this behavior, the end() function can be employed.

$myLastElement = end($yourArray);

This approach preserves the integrity of the array and returns the last element's value. However, it's important to note that end() also modifies the internal pointer of the array, affecting its subsequent iteration.

For PHP versions 7.3.0 and later, array_key_last() offers an alternative solution. This function returns the last key of the array without altering its internal pointer. The last element's value can then be obtained using the returned key:

$myLastElement = $yourArray[array_key_last($yourArray)];

By utilizing end() or array_key_last(), developers can retrieve the last element of an array without the risk of inadvertently modifying its structure.
