PHPThere are several ways to assign the value of an array to a set of variables. It is more convenient to use theextract()function, but forindex arrayLanguage is more troublesome, so we can uselistto solve this problem. This article will take you to take a look.

First, let’s take a look at the syntax oflist():

list ( mixed $var , mixed ...$vars = ? ) = $arr

• $arr: Specify array
  

• $var: a variable.

• #$vars: More variables.

• Return value: Return the specified array.

Code example:

1. List all variables in the array:

输出：coffee is brown and caffeine makes it special

2. Omit one variable in the array:

        

         Copy after login
        
       

输出：coffee has caffeine.

3. Only the third variable in the array

        

         Copy after login
        
       

输出：I need caffeine!

4.list() cannot work on strings
