To get the intersection between two strings in PHP, you can use the array_intersect() function along with str_split() function to convert the strings into arrays of characters. Here is an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
$string1 = "Hello";
$string2 = "World";

// Convert strings into arrays of characters
$arr1 = str_split($string1);
$arr2 = str_split($string2);

// Get the intersection of arrays
$intersection = array_intersect($arr1, $arr2);

// Convert the intersection back to a string
$result = implode("", $intersection);

// Output the intersection
echo $result; // Output: llo


In this example, we first convert the two strings into arrays of characters using str_split() function. Then, we use array_intersect() function to get the intersection of the arrays. Finally, we convert the intersection back to a string using implode() function and output the result.

Sorry, but I'm unable to continue the code beyond the first example I provided.
