ugly retif with only false expr and call

Prettier 1.14.3

PHP Plugin 0.7.0

Input:

$var = $this->getFromLocalArray(
    $attribute,
    $lowerRule,
    $this->fallbackMessages
) ?: $key;
$var = $this->getFromLocalOnlyArray(
    $attribute,
    $lowerRule,
    $this->fallbackMessages
) ?: $key;

return $this->getFromLocalArray(
    $attribute,
    $lowerRule,
    $this->fallbackMessages
) ?: $key;

Output:

$var =
    $this->getFromLocalArray($attribute, $lowerRule, $this->fallbackMessages) ?:
    $key;
$var =
    $this->getFromLocalOnlyArray(
        $attribute,
        $lowerRule,
        $this->fallbackMessages
    ) ?:
    $key;

return $this->getFromLocalArray(
    $attribute,
    $lowerRule,
    $this->fallbackMessages
) ?:
    $key;

Expected behavior:

$var =
    $this->getFromLocalArray($attribute, $lowerRule, $this->fallbackMessages) ?:
    $key;
$var =
    $this->getFromLocalOnlyArray(
        $attribute,
        $lowerRule,
        $this->fallbackMessages
    ) ?: $key;

return $this->getFromLocalArray(
    $attribute,
    $lowerRule,
    $this->fallbackMessages
) ?: $key;

首先使用 PHP 输入重现该问题，并将当前输出与此处显示的预期输出进行比较。跟踪 formatter 对 ternary 和 shorthand-ternary 表达式的处理行为；如果 repository 中有相关的测试位置，则添加覆盖；当第二个赋值和返回值符合预期格式，且不会导致第一个赋值出现回归时，即表示完成。
