php存储数组中的变量？ [关闭]

Question

I am just a newbie in php. So this question may be sound like childish. But I really want to know this.I saw in a php file one php code line was like this

$taxonomies = array();

Here it is looking like taxonomies is the variable stored in an array if I am not wrong. So can someone clear me what is the purpose of doing this?How the variable is stored in an array Any live example or any link will really clear my doubt.

Answer 1

This just defines that this variable is an array.
