How do I count items in an array PHP?You can simply use the PHP count() or sizeof() function to get the number of elements or values in an array. The count() and sizeof() function returns 0 for a variable that has been initialized with an empty array, but it may also return 0 for a variable that isn't set.
How can I get distinct values from an array of objects in PHP?The array_unique() function removes duplicate values from an array.
How do you get unique values in a multidimensional array?A user-defined function can help in getting unique values from multidimensional arrays without considering the keys. You can use the PHP array unique function along with the other array functions to get unique values from a multidimensional array while preserving the keys.
How do you find unique elements in an array?By using hashmap's key. In Java, the simplest way to get unique elements from the array is by putting all elements of the array into hashmap's key and then print the keySet(). The hashmap contains only unique keys, so it will automatically remove that duplicate element from the hashmap keySet.
