Syntax:void public DsVector::sort ($comparator)
Parameters: this function takes one parameter $comparator which is used to store the sorting function.Return value:This function does not return any value. The following programs illustrate the Ds / Vector::sort()function in PHP:Program 1:
// Declare a new vector $vect = new DsVector ([6, 5, 4, 3, 2, 1]); echo ( " Original vector " );
// Show vector elements print_r ( $vect );
// Use the sort() function to sort
// vector elements $vect -> sort(); echo ( " Sorted elements " );
// Show sorted vector
// elements print_r ( $vect );
?> Output:Original vector DsVector Object ([0] = > 6 [1] = > 5 [2] = > 4 [3] = > 3 [4] = > 2 [5] = > 1) Sorted elements DsVector Object ([0] = > 1 [1] = > 2 [2] = > 3 [3] = > 4 [4] = > 5 [5] = > 6)
Program 2:
// Declare a new vector $vect = new DsVector ([3, 6, 1, 2, 9, 7]); echo ( " Original vector " );
// Show vector elements print_r ( $vect );
// Use the sort() function to sort
// vector elements $vect -> sort ( function ( $element1 , $element2 ) { return $element2 < = > $element1 ; }); echo ( " Decreasing Sorted elements " );
// Show sorted vector
// elements print_r ( $vect );
?> Output:Original vector DsVector Object ([0] = > 3 [1] = > 6 [2] = > 1 [3] = > 2 [4] = > 9 [5] = > 7) Decreasing Sorted elements DsVector Object ([0] = > 9 [1] = > 7 [2] = > 6 [3] = > 3 [4] = > 2 [5] = > 1 )
