did you try `array_combine()` or `array_merge()` **Example: [array-merge.php](http://php.net/manual/en/function.array-merge.php)** — Murad Hasan, Jun 29 '17 at 06:46
You can merge by this function: http://php.net/manual/en/function.array-merge.php — Mohammadreza Yektamaram, Jun 29 '17 at 06:48
Simply add the arrays: `$array4 = $array1 + $array2 + $array1` see: https://stackoverflow.com/a/3292071/4121573 — Adonis, Jun 29 '17 at 12:20

If each array is on a variable you can do this,

$final=$arr1 + $arr2 + $arr3;

THat way you will not loose the keys as well. Check the manual here.

This is the correct answer. Using array_merge will discard numeric keys. – Ondra Koupil Jun 29 '17 at 06:52

Or

$array1 = array('1869' => 1,'1871' => 1,'0' => 2,'1807' => 1,'1875' => 1,'1811' => 1,'1877' => 1,'1878' => 1,'1879' => 1,'1880' => 1,'1886' => 1,'1850' => 2,'1618' => 3,'1679' => 1);
$array2 = array('1619' => 1,'1625' => 1);
$array3 = array('1111' => 1,'2222' => 1);

$newArray = array_replace( $array1,$array2,$array3);

But I think just using the + is preferred.

print_r($newArray);

Array combine with all as it is like same keys and values
