I think order precedence comes into play and '1' replaces true which returns '2'. Since false will not be evaluated. Looks like a language bug but i doubt its. #HappyCoding

it may sound crazy, but ternary in php is left-associative here's the proof https://www.php.net/manual/en/language.operators.precedence.php so true?'1':false?'2':'3' will become '1'?'2':'3' resulting '2' true?'1':false will get executed, then the the result is used for the next operation
