Example 5: Delete Item From Array when array consists of multiple repeated values using PHP
Remove all duplicated values. The original value will be deleted along with the duplicates.

    [3] => Alaska
    [4] => Texas
    [5] => Utah
    [6] => Alaska

Following are the array contents AFTER applying array_unique function. We get only the unique values and this will leave out multiple, repeated values

Array
(
    [0] => Texas
    [1] => Alabama
    [2] => New York
    [3] => Alaska
    [5] => Utah
)

Following are the array contents AFTER applying array_diff_assoc. This will leave the most unique, non-repeated values and will return an array of values that were repeated at least once:

Array
(
    [4] => Texas
    [6] => Alaska
    [7] => New York
)

Following are the array contents AFTER applying array_diff. This will leave the most unique, non-repeated values and will return an array of values that were repeated at least once. So the following is our FINAL DESIRED RESULT:

Array
(
    [1] => Alabama
    [5] => Utah
)
