Usually, we can search and identify PHP function just by looking at it’s name which denotes what a function does. For example array_pop(), array_push(), array_search(), array_reverse(), etc. But how about inserting an element into the middle of an array?
array_splice(array &$input, int $offset [, int $length= 0 [, mixed $replacement]] ) is the function that you are looking for. Format to use this function to add new element at certain position in an array is array_splice($array, $insert_position, 0, $element_to_insert);. See below for an example of how this function behaves.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | <?php $input = array("red", "green", "blue", "yellow"); array_splice($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"); ?> |
Thanks for the explaination
