Change case in string?

[stephdumais]

Hi, I looked at the documentation but I still cant quite figure out how to change the case of some of the letters in the following example:

My array is composed of file names such as:
section_one, section_two, section_three ect...

I want to print these out as titles like so:
Section One, Section Two, Section Three ect...

I already know how to replace the underscore with a space but how can I get my script to recongnize the space and give each new word an uppercase first letter?

this_file_is_an_example ==> This File Is An Example
ect..

Anyone?
Thanks

Hi,

If it only the output you want to change.. Look at the CSS coding of tekst.

http://www.w3.org/TR/REC-CSS2/text.html#caps-prop

:

16.5 Capitalization: the 'text-transform' property
'text-transform'
Value: capitalize | uppercase | lowercase | none | inherit

Initial: none

Applies to: all elements

Inherited: yes

Percentages: N/A

Media: visual

This property controls capitalization effects of an element's text. Values have the following meanings:

capitalize
Puts the first character of each word in uppercase.

$string = " my_string with_underscores ";

$string = str_replace ("_", " ", $string);

$string = ucwords ($string);

print ($string);

Ah, so "ucwords" is what I was looking for. Thanks!
As for the CSS solution, that wouldnt because while it is for output, I also needed it within the larger function.
