Detect Upper case characters in a string and separate them with a space

[zainally@gmail.com]

I want to detect uppercase characters in a string and separate the two
words in it by a space. I know I can use preg_replace for it, but I am
not very good at regular expressions. Can someone help?

One example of such a string follows. Please note that there are a lot
of strings like these and I want a generic method to do it, which is
why I think preg_replace would be the perfect solution. If someone can
help me, that would be great!

Example:

$string = "UserLocati on";

I want the string to be $string = "User Location";

You want something like this:

$s = preg_replace('/([^\s])([A-Z])/', '\1 \2', $s);

You probably want to consider what sort of behaviour is "desirable" in
edge cases like this:

Print404ErrorPa ge
GetHTTPRequest
Jpeg2Gif

The above regular expression will output:

Print404 Error Page
Get H T T P Request
Jpeg2 Gif

which might not be what you wanted!

Further to Toby's post:

$TestStr = Print404ErrorPa ge\nGetHTTPRequ est\nJpeg2Gif\n JPEG";

$CapRegX = '/(\B[A-Z])(?=[a-z])|(?<=[a-z])([A-Z])/sm';
$RepStr = ' $1$2';
$OutStr = preg_replace($C apRegX,$RepStr, $TestStr);

produces:

Print404 Error Page
Get HTTP Request
Jpeg2 Gif
JPEG
