Quick Reference
The PHP array_splice() function removes selected elements from an array and replaces it with new elements. The function also returns an array with the removed elements.
The keys in the replaced array are not preserved.
<?php
$a1 = array('Car 1' => 'Lamborghini', 'Car 2' => 'Ferrari', 'Car 3' => 'Maserati');
$a2 = array('Car 4' => 'Alfa Romeo', 'Car 5' => 'Porsche');
array_splice($a1, 0, 2, $a2);
print_r($a1);
?>Note
Arrays count starting from zero NOT one. So item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on.
Output
Array ( [0] => Alfa Romeo [1] => Porsche [Car 3] => Maserati )Syntax
array_splice(array, start, length, replacement)Parameters
| Parameter | Description |
|---|---|
| array | Specifies an array (required) |
| start | Specifies where the function will start the slice; 0 = the first element; if this value is set to a negative number, the function will start slicing from the last element (-2 would start at the second from the last element (required) |
| length | Specifies the length of the returned array; if this value is set to a negative number, the function will stop slicing that far from the last element; f this value is not set, the function will return all elements, starting from the position set by the start parameter |
| replacement | Specifies an array with the elements that will be inserted to the original array; if it's only one element, it can be a string, and does not have to be an array |
PHP Notes:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
