#14655 [Com]: ucwords failing randomly with international characters

ID: 14655 Comment by: fille@fukt.bth.se Reported By: xtango@netcombbs.com.ar Status: Assigned Bug Type: Strings related Operating System: Windows XP Pro (spanish) PHP Version: 4.1.0 Assigned To: hholzgra New Comment: I had this bug to. To get around it, I added some 'hair' to the code. $string=ucwords($string); //Bugfix from here on for($i=0;$i<strlen($string);$i++) if((ctype_upper($string[$i]) &&( $string[$i-1]==" " || $i==0 ))!=TRUE) $string[$i]=strtolower($string[$i]); I'm a PHP newbie so I guess some of you can come up with a brighter solution. This code lowercases _all_ letters that is not either the first in the string or following a space. If your application does not meet both this criterias, you might not want this code.

PHP only uses the systems notion of upper and space. When the character following the international character it is probably because the international character is treated as a space by the system (isspace() returning true). It's quite weird that the results are not consistent. The PHP function itself is quite straightforward, so I suspect the locale is not the same every time, or that the systems isspace() and possibly toupper() is broken. I can't say for sure though. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
