PHP loop and return $key of multidimensional array

I'm trying to write a PHP function to loop into a multidimensional array to match it with a business name then return to me the "business type".

With my current skills, I wrote this function but I would like to know if there's a better solution other than looping twice because my real arrays are much bigger than the example below.

Note: I'm a student, I already searched StackOverflow but couldn't find my need.

function find_business_type($dealer_name) {
    $business_type = [
        "OEM"               => ["kia", "mercedes"],
        "Rent"              => ["rent", "rent-a-car"],
        "Workshop"          => ["shop", "workshop"],
        "Spare Parts"       => ["spare", "parts", "part"],
        "General Trading"   => ["gen", "general"]
    ];

    foreach ($business_type as $key => $values) {
        foreach ($values as $value) {
            if (strpos($dealer_name, $value) !== false) {
                return $key;
            }
        }
    }
}


$my_dealer = "super-stars-123 rent a car";
echo find_business_type($my_dealer);

Output: "Rent"

Here's an idea. Essentially, you can filter the array and grab all the rows that match your string based on a percent. Note that array_filter will return an array with all the matching values not just one match.

    <?php

$dealer = "super-stars-123 rent a car";

$types = [
        "OEM"               => ["kia", "mercedes"],
        "Stars"             => ["super-stars", "123"],
        "Brown"             => ["super stars", "abc"],
        "Home"              => ["think rent", "123"],
        "Super"             => ["renter", "car"],
        "Rent"              => ["rent", "rent-a-car"],
        "Workshop"          => ["shop", "workshop"],
        "Spare Parts"       => ["spare", "parts", "part"],
        "General Trading"   => ["gen", "general"]
    ];

// Filter through your array
$results = array_filter($types, function($type) use ($dealer) {
    // explode your inner array to a string and then try to match it
    // to your search dealer text. This returns a % match.
    // I would play around with this algo logic below to get it to do what you want.
    return (similar_text($dealer, implode(", ",$type), $percent) >= 8);
});

var_dump($results);   

 array (size=4)
  'Stars' => 
    array (size=2)
      0 => string 'super-stars' (length=11)
      1 => string '123' (length=3)
  'Brown' => 
    array (size=2)
      0 => string 'super stars' (length=11)
      1 => string 'abc' (length=3)
  'Super' => 
    array (size=2)
      0 => string 'renter' (length=6)
      1 => string 'car' (length=3)
  'Rent' => 
    array (size=2)
      0 => string 'rent' (length=4)
      1 => string 'rent-a-car' (length=10)
