What Is Title Case — and Why Does It Matter More Than You Think?

Title case is a capitalization style where the first letter of major words in a title, heading, or headline is capitalized, while minor words (like "a," "the," "in," "of") are left lowercase — unless they appear at the beginning or end of the title.

That’s where a Title Case Converter Online becomes essential. Instead of manually second-guessing every word, you paste your text, click a button, and get perfectly capitalized output in under a second — following whatever style guide rules you need.

    result = []
    for i, word in enumerate(words):
        if i == 0 or i == len(words) - 1 or word not in minor_words:
            result.append(word.capitalize())
        else:
            result.append(word)
    return ' '.join(result)

# Usage:

function toTitleCase(string $str): string {

                   'by','of','up','as','if'];
    $words = explode(' ', strtolower($str));
    $last = count($words) - 1;

    foreach ($words as $i => &$word) {
        if ($i === 0 || $i === $last || !in_array($word, $minorWords)) {
            $word = ucfirst($word);
        }
    }
    return implode(' ', $words);
