在PHP5.6的环境中报错

哥们儿，我知道你是中国人，我就不跟你扯英文了。

这个东西在PHP5.6环境中报错了：

PHP Fatal error: Cannot use OpenTracing\SpanContext as SpanContext because the name is already in use in /home/manhong/jeager/vendor/jukylin/jaeger-php/src/Jaeger/Span.php on line 5
PHP Stack trace:

只要注释掉 “vendor/jukylin/jaeger-php/src/Jaeger/Span.php” 文件中的 “use OpenTracing\SpanContext;“ 这一行就可以了。

我是用composer安装的，安装步骤如下：
composer require opentracing/opentracing 1.0.0-beta2
composer require jukylin/jaeger-php v2.0.5-beta

你好，你们公司在用php 5.6 吗？

[jukylin]

我在mac 使用brew 安装不了5.6 ，所以验证不了这个问题。我现在打算不兼容5.6了。

唉~小公司，资源有限，没办法。我自己再想想办法吧......
