Is there any PHP function to solve out array value matches in another array value string?

Question

I am creating a word search but I want to rank them base on the highest existence of search keyword. How can I solve this problem?

I am trying to make a search if array 1 key exists inside array 2 long string and then order the array by total occurrence of array 1 in array 2.

Blow is my code

$str = "Hello World January Jude";
$arr1 = ["Hello World January Jude Lol Love","Hello Lol Loop","Love Life Jude","Crude Flash Hello"];
$str = explode(" ", $str);
echo sort_base($arr1, $str);
function sort_base($arr, $str){
$count = "";
foreach ($arr as $valuer){
    foreach ($str as $value){
    //$list[] = strpos($valuer, $value, 0);
    $count .= strpos($valuer, $value, 0)."<hr/>"; 
}

}
$arr = trim($count," ");
 echo $arr;
}

Example input:

$array = ["Say Hello","Hello World"," Hello World Cup Final","Hello Cup","Hello","World"]; 
$str = "Hello World Cup"; 

Desire output:

Array in order:

1. Hello World Cup
2. Final Hello World
3. Hello Cup
4. Hello
5. World
6. Say Hello

Answer 1

You can use array-intersect and count to achieve number value of the similar words. Now you can use usort for sort by that.

Consider the following:

function sort_most_exists_asc($arr, $str) {
    usort($arr, function ($a, $b) use ($str) {
        $aa = count(array_intersect(explode(" ", $str), explode(" ", $a)));
        $bb = count(array_intersect(explode(" ", $str), explode(" ", $b)));
        return $bb - $aa;
    });
    return $arr;
}

$str = "Hello World January Jude";
$arr = ["Hello World January Jude Lol Love","Hello Lol Loop","Love Life Jude","Crude Flash Hello"];
$arr = sort_most_exists_asc($arr, $str);

Live example: 3v4l

Notice this will work only for whole words. For words similarity use Levenshtein distance - and compare by that in the usort

Answer 2

You can create a set of all the matching words between each phrase and the target list of words.

foreach ($arr1 as $phrase) {
    $matches[] = array_intersect(str_word_count($phrase, 1), $str);
}

That array of matches can be used with array_multisort to reorder the original array.

array_multisort($matches, SORT_DESC, $arr1);
