What is the best way to capitalize a string?

[fundflow]

Is there a better way to capitalize a string than
s/(\w+)/\u$1/g
?

A couple (better?) ways come to mind:

$string = uc($string);

$string =~ tr/a-z/A-Z/;

Try the internal function uc. To capitalize just the first character, try ucfirst. This has the additional benefit of respecting any locale you have set.

You can use uc or lc built-in functions to change case. If you wanto to change case of first character only, then use ucfirst or lcfirst functions.



$lower = "name";
$upper = "NAME";
print uc($lower),"\n"; ### This will print : NAME
print lc($upper),"\n"; ### This will print : name
print ucfirst($lower),"\n"; ## This will print : Name
print lcfirst($upper),"\n"; ## This will print : nAME
