Definition and Usage
The join() function returns a string from the elements of an array.
The join() function is an alias of the implode() function.
Note: The join() function accept its parameters in either order. However, for consistency with explode(), you should use the documented order of arguments.
Note: The separator parameter of join() is optional. However, it is recommended to always use two parameters for backwards compatibility.
Syntax
join(separator,array)
Example
Join array elements with a string:
<?php
$arr = array('Hello','World!','Beautiful','Day!');

?>

$array2 = [2, 1, 8, 3];
//Method 1:
array_filter($array1, function($_){
global $array2;
return in_array($_, $array2);
}); // Output: [0 => 1, 3 => 2]
