You need to add /usr/local/binto your PATHvariable. The easiest way is to throw it in your profile or bash_profile located at either:
您需要添加/usr/local/bin到您的PATH变量中。最简单的方法是将其放入您的个人资料或位于以下任一位置的 bash_profile 中：
- ~/.profile
- ~/.bash_profile
- ~/.profile
- ~/.bash_profile
You would add the following to one of those files:
您可以将以下内容添加到其中一个文件中：
export PATH="$PATH:/usr/local/bin/"

If you are logged in when you add it, you can force Linux to read the file again and update the path (once the changes are made) by using sourcefrom the bash prompt:
如果您在添加文件时已登录，则可以source在 bash 提示符下使用：
source ~/.bash_profile
As for the php7vs. phpissue, as Alex suggested, you can make a symlink so it works kinda like an alias.
至于php7vs.php问题，正如亚历克斯所建议的那样，您可以创建一个符号链接，使其有点像别名。
