php - Multiple boolean conditions - operator precedence

Question

I encountered a code line that looks like this:

if ($users == 'all' || $_POST['user'] == 1 && $users == 'admins' || $_POST[ 'user' ] == 0 && $users == 'mods') ...

I don't understand how are all these conditions met because there are not parentheses between them :(

Is || more important than && ? Which parts get evaluated first?

Answer 1

&& depends of the evaluation of the right expression when left one is true, || doesn't. You could rewrite it to:

if(
    $users == 'all' ||
    ($_POST['user'] == 1 && $users == 'admins') ||
    ($_POST['user'] == 0 && $users == 'mods')
)

And it'll be the same.
