PHP two functions for splitting a fractional group (Array_slice (), Array_splice ())

$input = Array ("A", "B", "C", "D", "E"); $output = Array_slice ($input, 2); Returns "C", "D", and "E" $output = Array_slice ($input,-2, 1); Returns "D" $output = Array_slice ($input, 0, 3); Returns "A", "B", and "C" Note the differences in the array keys Print_r (Array_slice ($input, 2,-1)); Print_r (Array_slice ($input, 2,-1, true)); ?> Copy Code The example above will output: Array ([0] = c[1] + d) Array ([2] = c[3] + D) 2.array_splice () Carry three parameters, ibid., to delete a subarray of length from offset. Example: $input = Array ("Red", "green", "blue", "yellow"); Array_splice ($input, 2); $input is now array ("Red", "green") $input = Array ("Red", "green", "blue", "yellow"); Array_splice ($input, 1,-1); $input is now array ("Red", "yellow") $input = Array ("Red", "green", "blue", "yellow"); Array_splice ($input, 1, Count ($input), "Orange"); $input is now array ("Red", "orange") $input = Array ("Red", "green", "blue", "yellow"); Array_splice ($input,-1, 1, Array ("Black", "maroon")); $input is now array ("Red", "green", "Blue", "Black", "maroon") $input = Array ("Red", "green", "blue", "yellow"); Array_splice ($input, 3, 0, "purple"); $input is now array ("Red", "green", "Blue", "purple", "yellow"); ?> Copy Code
