When using ucwords() on a string which contains words in  
parenthesis, the first word in the parenthesis is not  
capitalized.  
  
Here's a quick example, pasted from an xterm.  
  
-- snip --  
ieure!Phaktory:~$ cat ucwords.php  
#!/usr/bin/php4 -q  
<?php 
echo ucwords($_SERVER['argv'][1])."\n";  
?>  
ieure!Phaktory:~$ ./ucwords.php 'test'  
Test  
ieure!Phaktory:~$ ./ucwords.php 'test test'  
Test Test  
ieure!Phaktory:~$ ./ucwords.php 'test test (test)'  
Test Test (test)  
ieure!Phaktory:~$ ./ucwords.php 'test test (test test)'  
Test Test (test Test)  
ieure!Phaktory:~$ ./ucwords.php 'test test ( test test)'  
Test Test ( Test Test)  
ieure!Phaktory:~$  
-- snip --  
  
As you can see, ucwords() won't capitalize the first 'test'  
when there is no whitespace between the open-parenthesis  
and the first letter.  
  
Affects both CGI and Apache module versions. Here's the 
script I used to test the apache module: 
 
<?php 
echo ucwords($_GET['string']); 
?>
