List language structure in notes 012PHP

PHP has something similar to function usage, called the syntax structure. This feature is generally introduced in the function. Currently, Hy369 has the following syntax structures: echo, print, and array. Of course, the list mentioned here is also a syntax structure.

Currently, Hy369 has the following syntax structures: echo, print, and array. Of course, the list mentioned here is also a syntax structure.

There are no other syntax structures, and Hy369 is not particularly focused on this, so it is not very clear. I will pay attention to it later.

The function of list is to assign values to a group of variables using arrays. Its syntax is:

list(var1,var2...)

You can easily assign values in the array to the specified variable through list. Here are two examples:

 "Dog","b"=>"Cat","c"=>"Horse");print_r($a);

Output result:

Array ( [a] => Dog [b] => Cat [c] => Horse )

 
Here I only use the Dog and Horse variables.
Pay attention to the second example. Previously, Hy369 wrote code similar to list ($ a, $ B, $ c) = $ array to get the value of a non-first array, then output the value of $ c that I only need. At that time, I still don't know how to directly write it into list (, $ c) = $ arra (note the comma ). I want to think about it now, but I still feel a little ashamed.
