echo ucwords($text); // Php String Functions
$str="welcome to plus2net.com. you can learn web programming here";
$str=ucwords($str);
echo $str;

$input_str = "welcome everyone";
$output = ucwords($input_str);

$str = 'hello-world_php-tutorial';
echo ucwords($str, "-_"); // Output: Hello-World_Php-Tutorial
Example: Unicode title casing (mbstring)
ucwords() is ASCII-oriented. For Unicode title casing, use mb_convert_case() if mbstring is installed; title-casing rules vary by language.
$str = 'привет мир';
echo mb_convert_case($str, MB_CASE_TITLE, "UTF-8"); // Outputs: Привет Мир (with mbstring)
