arsort -- 
     Sort an array in reverse order and maintain index association
    
Description
void 
arsort ( array array [, int sort_flags])
     This function sorts an array such that array indices maintain
     their correlation with the array elements they are associated
     with.  This is used mainly when sorting associative arrays where
     the actual element order is significant.
    
| Example 1. arsort() example | $fruits = array ("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
arsort ($fruits);
reset ($fruits);
while (list ($key, $val) = each ($fruits)) {
    echo "$key = $val\n";
} | 
 
      This example would display:
       | a = orange
d = lemon
b = banana
c = apple | 
 | 
     The fruits have been sorted in reverse alphabetical order, and
     the index associated with each element has been maintained.
    
     You may modify the behavior of the sort using the optional
     parameter sort_flags, for details
     see sort().
