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

Also, you can condense goat's answer in the event it's not a binary:

if (count(array_unique($allvalues)) === 1 && end($allvalues) === 'true') {
   // ...
}

to

if (array_unique($allvalues) === array('foobar')) { 
   // all values in array are "foobar"
}
