php function Shuffle () implementation reordering _php Tutorial

In

Shuffle--The array is scrambled:
BOOL Shuffle (array &array)

php function Shuffle () An array of scrambled (randomly arranged cells).

Note: The PHP function shuffle () assigns a new key name to the cells in the array. This will delete the original key name and not just reorder it.

Example:

 
 

  
  

  
< ? PHP
  
  

  
$ a  =  Array ( 
  
  

  
' 1 ' = > ' Xiao ',
  
  

  
' 2 ' = > ' Da ',
  
  

  
' 3 ' = > ' Zuo ',
  
  

  
' 4 ' = > ' You '
  
  

  
);
  
  

  
echo "original array:". " <    br  />"; 
  
  

  
Print_r ($a);
  
  

  
Shuffle ($a);
  
  

  
echo " <    br  />"." Now the array: "." <    br  />"; 
  
  

  
Print_r ($a);
  
  

  
?>  
 
 

Look at the results of the PHP function shuffle ():

The original array:

Array ([1] = Xiao [2] = Da [3] = Zuo [4] = =--)

Now the array:

Array ([0] = Da [1] = Xiao [2] = = [3] = = Zuo)

Of course, each time the page is refreshed, the order of the elements in the "now array" is changed once. Note that the key name of the array has changed.
