What is the php end method for?

In php, the end () function points the pointer inside the array to the last element of the array (at this point) and returns the value of the last element, or FALSE if the array is empty.

The syntax format of the end () function is as follows:

End ($array)

The parameter $array is the array to be operated on.

Return value: returns the value of the last element in the array if successful, or FALSE if the array is empty.

Example:

Using the end () function and the key () function, you can also get the key name of the last element of the array.

The end () function points the internal pointer to the last element of the array (where the last element is the current element of the array), and then uses the key () function to get the key name of the current element.
