Insert new item in array on any position in PHP

Insert new item in array on any position in PHP

In PHP, you can insert a new item into an array at any position using the array_splice() function. Here's an example:

// Original array $array = array('apple', 'banana', 'cherry', 'date'); // New item to insert $newItem = 'orange'; // Position to insert (0-based index) $insertPosition = 2; // Insert the new item into the array array_splice($array, $insertPosition, 0, $newItem); // Output the modified array print_r($array);

In this example:

  • $array is the original array.
  • $newItem is the item you want to insert.
  • $insertPosition is the position (0-based index) where you want to insert the new item.
  • array_splice($array, $insertPosition, 0, $newItem) inserts the new item into the array at the specified position without removing any elements.
  • Finally, print_r($array) prints the modified array.

After running this code, the output will be:

Array ( [0] => apple [1] => banana [2] => orange [3] => cherry [4] => date )

You can see that the $newItem 'orange' has been inserted into the array at the specified position (index 2).
