Quick Reference
The PHP array_merge() function merges one or more arrays into one array. If two or more elements have the same key, the last one overrides the others.
<?php
$a1 = array('Lamborghini', 'Ferrari');
$a2 = array('Maserati', 'Alfa Romeo');
print_r(array_merge($a1, $a2));
?>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] => Lamborghini [1] => Ferrari [2] => Maserati [3] => Alfa Romeo )Syntax
array_merge(array1, array2, array3, ...)Parameters
| Parameter | Description |

| array1 | Specifies an array (required) |

| array3, ... | Specifies additional arrays |
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.
