Perl string lcfirst() function - Quick Tutorial

How to use the string lcfirst() function

$STRING = lcfirst($STRING);

Perl's lcfirst() function takes a string, makes the first character lowercase, and then returns the new string.

$myWord = 'WORD';
$myLowerWord = lcfirst($myWord);

First, $myWord is set to a value of 'WORD', then the lcfirst() function is run on $myWord. The lcfirst() function takes the first character of $myWord (in this case 'W') and converts it to it's lowercase equivalent. The value of $myLowerWord is then equal to 'wORD'.

This function isn't particularly useful, and is probably just added in for a sense of balance with the ucfirst function.
