Answer 1

function findLongestStringSize(array $strings): int {
    $longestSize = 0;

    foreach ($strings as $string) {
        $stringSize = strlen($string);
        if ($stringSize > $longestSize) {
            $longestSize = $stringSize;
        }
    }

    return $longestSize;
}

$strings = ["c++", "php", "python", "c#", "java", "swift"];

$longestSize = findLongestStringSize($strings);

echo "The longest string size is: $longestSize\n";
