I've 2 arrays:
{"1":"red"}
{"1":"green","2":"red"}
It should remove 1 = green and replace it with 1 = red. Key 2 must simply remain.
So, I want an array like this:
{"1":"red","2":"red"}
How can I do that in PHP?

It's already fixed. The array 1 + array 2 fixed it ;)stijnb1234– stijnb12342018-02-26 18:54:23 +00:00Commented Feb 26, 2018 at 18:54

You could use the operator + :
$a = [1 => "red"] ;
$b = [1 => "green", 2 => "red"] ;
print_r($a + $b) ;
Outputs :
Array
(
[1] => red
[2] => red
)
From documentation :
The + operator returns the right-hand array appended to the left-hand array; for keys that exist in both arrays, the elements from the left-hand array will be used, and the matching elements from the right-hand array will be ignored.
