How to convert the first letter of a word to uppercase in PHP?

To convert the first letter of a word to uppercase in PHP, you can use the ucfirst() function. This function converts the first character of a string to uppercase, and returns the modified string.

For example:

$string = 'hello';
$string = ucfirst($string);

// $string will be equal to 'Hello'

You can also use the mb_strtoupper() function to convert the first character of a multibyte string to uppercase. This function requires the mbstring extension to be enabled in your PHP configuration.

For example:

$string = 'héllo';
$string = mb_strtoupper(mb_substr($string, 0, 1)) . mb_substr($string, 1);

// $string will be equal to 'Héllo'
