What potential issue can arise when using the ucwords() function in PHP for form validation?

The potential issue that can arise when using the ucwords() function for form validation is that it capitalizes the first letter of every word in a string, which may not be the desired behavior for all form inputs. To solve this issue, you can instead use the ucfirst() function, which only capitalizes the first letter of the string. 

// Example of using the ucfirst() function for form validation
$name = "john doe";
$capitalizedName = ucfirst(strtolower($name)); // Capitalize the first letter of the name
echo $capitalizedName; // Output: John doe
