Setting variable value on PHP ternary case -


i trying use ternary output 2 things on latter case.

the issue have setting text value variable in latter case, after incrementing error count.

i have tried few things, here's 2 attempts, these both fail on setting $errors_log value.

q. how can set variable value within output of ternary.

$errors_v=0; if (validate_username() == false ? null : $errors_v++ && $errors_log='username invalid');  if ($errors_v != 0) {     echo $errors_log; }  function validate_username() {     return true; }  $errors_v=0; $errors_log[]; if (validate_username() == false ? null : $errors_v++ && $errors_log[]='username invalid');  if ($errors_v != 0) {     var_dump($errors_log); }  function validate_username() {     return true; }

i ternary below, , check if $errors_log not empty , if it's not, print out errors.

$errors_log[] = validate_username() === false ? null : 'username invalid';  if (!empty($errors_log)) {     foreach($errors_log $error) {         echo $error;     } }  function validate_username() {     return true; }

if it's needed have counter aswell, though recommend count on $errors_log array instead, this:

if (!validate_username()) {     $errors_log[] = 'username invalid';     $errors_v++; }
