ucwords(strtolower()) not working together php-CodePudding

I have code where I am extracting a name from a database, trying to reorder the word, and then changing it from all uppercase to word case. Everything I find online suggests my code should work, but it does not... Here is my code and the output:

$subjectnameraw = "SMITH, JOHN LEE";
$subjectlname = substr($subjectnameraw, 0, strpos($subjectnameraw, ",")); // Get the last name 
$subjectfname = substr($subjectnameraw, strpos($subjectnameraw, ",")   1) . " "; // Get first name and middle name
$subjectname = ucwords(strtolower($subjectfname . $subjectlname)); // Reorder the name and make it lower case / upper word case

However, the output looks like this:

John Lee smith

The last name is ALWAYS lowercase no matter what I do. How can I get the last name to be uppercase as well?

CodePudding user response：

The above code gives wrong results when there are multibyte characters in the names like RENÉ. The following solution uses the multibyte function mb_convert_case.

$subjectnameraw = "SMITH, JOHN LEE RENÉ";
list($lastName,$firstnName) = explode(', ',mb_convert_case($subjectnameraw,MB_CASE_TITLE,'UTF-8'));
echo $firstnName." ".$lastName;
