Check if all values in array are the same

Question

I need to check if all values in an array equal the same thing.

For example:

$allValues = array(
    \'true\',
    \'true\',
    \'true\',
);
         


        

Answer 1

Why not just compare count after calling array_unique()?

To check if all elements in an array are the same, should be as simple as:

$allValuesAreTheSame = (count(array_unique($allvalues)) === 1);

This should work regardless of the type of values in the array.
