Are there any best practices or considerations to keep in mind when converting the first letter of each word in a string to uppercase in PHP to ensure accuracy and consistency?

When converting the first letter of each word in a string to uppercase in PHP, it is important to consider the use of the ucwords() function. This function will capitalize the first letter of each word in a string, while also taking into account word boundaries and handling special cases like apostrophes. By using ucwords(), you can ensure accuracy and consistency in the capitalization of words within a string.

$string = "hello world";
$capitalizedString = ucwords($string);
echo $capitalizedString;
