Question

I came across this php ucfirst() to make uppercase the first character of each word in a string.

$foo = 'hello world!';
$foo = ucfirst($foo); 

but how can I use use regular expression and preg_match() to check, then display the error message?

if (preg_match('/\b\p{Ll}/', $mem_titlename))
{
   $error = true;
   echo '<error elementid="mem_titlename" message="TITLE - please use uppercase for each word."/>';
}

not sure what that expression means in the example above but I got it from somewhere which does the same job as ucfirst()…

Answer 1

Why use a regular expression? It seems unnecessary if ucwords() does what you want. If so, just the following:

if (ucwords($mem_titlename) == $mem_titlename) {
   $error = true;
   echo '<error elementid="mem_titlename" message="TITLE - please use uppercase for each word."/>';
}

Also note that ucwords() does what you describe, not ucfirst(). http://www.php.net/manual/en/function.ucwords.php
