How to push a found array item into another array?

Question

I have an array. But trying to separate items. For example:

$array1 = ["banana","car","carrot"];  

trying to push car into another array which is $array2

$push = array_push($array1, "car") = $array2;

I try to find array_push usage for this but the documentation is all about. sending new item to array. Not array to array. Is this possible with array_push or need to use something else?

I need to search for the value car in $array1, push it into $array2 and remove it from $array1.

Here is a flexible solution that allows you to search by "car", then IF it exists, it will be pushed into the second array and omitted from the first.

Code: (Demo)

$array1 = ["banana","car","carrot"];  
$needle = "car";
if (($index = array_search($needle, $array1)) !== false) {
    $array2[] = $array1[$index];
    unset($array1[$index]);
}

var_export($array1);
echo "\n---\n";
var_export($array2);

Output:

array (
  0 => 'banana',
  2 => 'carrot',
)
---
array (
  0 => 'car',
)
