Php takes different values from the array

1. Using the array_unique () function:

The array_unique () function removes duplicate values from the array. If two or more array values are the same, only the first value is retained and the other values are removed.

2. Using array_keys () and array_count_values () functions

The array_count_values () function is used to count the number of occurrences of all values in the array. The key name in the returned array is the value of the original array, and the key value is the number of times the value appears in the original array.

The array_keys () function returns a new array containing all the key names in the array.
