Check for same Array values

I want to check in a single statement, if the contents of array are same or not. This is actually a challenge for me, but I am not able to check for the uniqueness of the values inside an array.

Also I want to make sure that the values are same as, say "S". Example array:

$myArray = array("S", "S", "S");  // true
$myArray = array("S", "S", "s");  // false

Is it possible using a single statement? Thanks in advance.

Yes, possible with array_count_values. Is this what you are looking for?

The function array_count_values() will count the number of unique values in the array. If you get the count of it to be 1, it is then unique like you said.

count(array_count_values($myArray)) == 1

Also, you can check one of the array values to be whatever value you wanted to check.

$myArray[0] == "S"

So combining these two in a single condition:

count(array_count_values($myArray)) == 1 && $myArray[0] == "S"

This will return true or false.

Full Working Code

<?php
    // Let's have two arrays.
    $myArray1 = array("S", "S", "S");  // Should return true
    $myArray2 = array("S", "S", "s");  // Should return false

    // Our function
    function checkArray($theArray, $value) {
      return count(array_count_values($myArray)) == 1 && $myArray[0] == $value;
    }

    // Checks
    checkArray($myArray1, "S"); // true
    checkArray($myArray2, "s"); // false
