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

$alltrue = 1;
foreach($array as $item) {
    if($item!='true') { $alltrue = 0; }
}
if($alltrue) { echo("all true."); }
else { echo("some false."); }

Technically this doesn't test for "some false," it tests for "not all true." But it sounds like you're pretty sure that the only values you'll get are 'true' and 'false'.
