Counting vallues in a array with spelcial character

I want to count all the values (The name of the cities) in this array who have the character t before the last character in the string.

ARRAY

$cities_array = array(
"city1" => "Paris_t1",
"city2" => "Madrid_t1",
"city3" => "Amsterdam_t1",
"city4" => "London_i1",
"city5" => "Miami_i1",
"city6" => "Berlin_i1",
"city7" => "Brussels_i1",
"city8" => "Toronto_i1",
);

The results should be: 3 (Paris_t1 - Madrid_t1 - Amsterdam_t1)

I believe i have to combine:

array_count_values($cities_array)

and

substr($value, -2, 1) == "t"

I have tried, but I get only errors.

Try below solution:

$cities_array = array(
    "city1" => "Paris_t1",
    "city2" => "Madrid_t1",
    "city3" => "Amsterdam_t1",
    "city4" => "London_i1",
    "city5" => "Miami_i1",
    "city6" => "Berlin_i1",
    "city7" => "Brussels_i1",
    "city8" => "Toronto_i1",
);

$filtered_array = array_filter($cities_array, function($val){
    return (strpos($val, 't', (strlen($val)-2)) !== false);
});

print_r($filtered_array);

output: - (you can implode array by - to get desired result)

Array
(
    [city1] => Paris_t1
    [city2] => Madrid_t1
    [city3] => Amsterdam_t1
)

In above solution in strpos third parameter strlen($val)-2) i.e. position will be searched from second last character of $val

This will give you what you want.

        $cities_array = array(
                "city1" => "Paris_t1",
                "city2" => "Madrid_t1",
                "city3" => "Amsterdam_t1",
                "city4" => "London_i1",
                "city5" => "Miami_i1",
                "city6" => "Berlin_i1",
                "city7" => "Brussels_i1",
                "city8" => "Toronto_i1",
                );
$count = 0;
$city_text = '';
foreach($cities_array as $city){
    if(substr($city, -2, 1) == "t"){
        $count++;
        $city_text .= $city . '-';
    }
}

echo $count. "(".rtrim($city_text,'-').")";
