How do I capitalize all the words in a string?


You could write a few lines of code or simply use a regular expression. The second solution might be more what you're looking for.

# Capitalizes all words - this will turn 
#      don't feed ducks
# into 
#      Don'T Feed Ducks
#          ^--!

$sentence =~ s/\b(\w)/\U$1/g;

# a better solution, taking care of such situations:
$sentence =~ s/(
                 (^\w)    #at the beginning of the line
                   |      # or
                 (\s\w)   #preceded by whitespace
$sentence =~ /([\w']+)/\u\L$1/g;

Content-type: text/html

In PHP 4 or greater, use the built-in PHP function:

$test = ucwords( 'set me to uppercase.' );

Results: 'Set Me To Uppercase.'
