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

If your array contains actual booleans (or ints) instead of strings, you could use array_sum:

$allvalues = array(TRUE, TRUE, TRUE);
if(array_sum($allvalues) == count($allvalues)) {
    echo 'all true';
} else {
    echo 'some false';
}

This works because TRUE will be evaluated as 1, and FALSE as 0.
