【问题描述】：
我已经设置了 Eclipse Oxygen.1 4.7.1 (Build 20170914-1200) 来处理基于 Symfony 的 PHP 项目。
一切正常，但出现的亮点（例如局部变量、方法等）。
public function someMethod($paramA) {
doSomething($paramA);
...
$var = $paramA;
}
当我将光标放在方法签名中的$paramA 中时，我希望在方法主体中出现$paramA 会突出显示。前段时间使用 Ecplise Mars 时肯定是这种情况。知道为什么这不起作用吗？
我已经检查了Preferences/PHP/Editor/Mark/Occurrences，所有选项都已检查/激活。
Preferences/General/Editors/Text Editors/Annotations/Occurrences 似乎也设置正确（垂直标尺：否，概览标尺：是，文本作为突出显示，颜色：灰色，包含在下一个/上一个导航中：否）
还有其他需要检查的偏好吗？
