combine or intersect two arrays different length in php - php

Question

First array is $niz:
Array (
[Swansea] => 4
[Stoke City] => 3
[Sunderland] => 3
[Southampton] => 5
[Liverpool] => 3
[Manchester United] => 2
[Hull City] => 1
[Tottenham] => 2
[Newcastle Utd] => 1
[Aston Villa] => 1
[West Ham] => 2
[Crystal Palace] => 3
[Chelsea] => 3
)
Second array is $niz1:
Array (
[Stoke City] => 2
[Sunderland] => 2
[Liverpool] => 1
[Hull City] => 1
[Tottenham] => 1
[Manchester United] => 1
[Newcastle Utd] => 1
[Crystal Palace] => 3
[Chelsea] => 1
)
How to combine these arrays to get $niz2 (keys are ordered like array $niz1 and values are from matching array $niz) like:
$niz2:
Array (
[Stoke City] => 3
[Sunderland] => 3
[Liverpool] => 3
[Hull City] => 1
[Tottenham] => 2
[Manchester United] => 2
[Newcastle Utd] => 1
[Crystal Palace] => 3
[Chelsea] => 3
)
I tried with function array_merge() but I get empty values and I tried with array_intersect_key().

Answer 1

try this
foreach ($niz1 as $k=>$n)
{
if(in_array($k,$niz1))
{
$niz2[$k]=$niz[$k];
}
}
print_r($niz2);

Answer 2

Try this:
$temp = array_intersect_key($niz, $niz1);
foreach ($niz1 as $k => $v) {
$niz2[$k] = $temp[$k];
}

Answer 3

//(overwrites the values of $niz1 with those of $niz2)
$bif=array_merge($niz1,$niz);
//(removes everything from $bif that is not in $niz1)
$result=array_intersect($niz1,$bif);
