similar_text最高字符串值

Question

I use similar_text to find which string have the highest similar value to the input

I tried using rsort to get the highest value, but how do I get string which have the highest value?

$similarities = [];
$input = "makanan daerah";
$type = array('pakaian','senjata','makanan', 'tarian');
foreach ($type as $value) {
    similar_text($input, $value, $percent);
    $similarities[$value] = $percent;
}
rsort($similarities);
echo($similarities[0]);

I expect output makanan but the only output I can display is the percent value 66.6667

Answer 1

We can try using asort to sort the associative array of terms and percentages by the latter. Then, access the last key, which should coincide with the key having the highest percentage:

$similarities = [];
$input = "makanan daerah";
$type = array('pakaian','senjata','makanan', 'tarian');
foreach ($type as $value) {
    similar_text($input, $value, $percent);
    $similarities[$value] = $percent;
}
asort($similarities);
print_r($similarities);
end($similarities);
$key = key($similarities);
var_dump($key);

Array
(
    [senjata] => 19.047619047619
    [tarian] => 30
    [pakaian] => 47.619047619048
    [makanan] => 66.666666666667
)
string(7) "makanan"
