case sensetivity

[qwicker]

how can i do an if statement to compare to variables, regardless of their case sensetivity.
Lets say i have $a = ABC and $b = Abc. I want a value of true that $a==$b

if (lc($a) eq lc($b) ) {
do somthing
}

note == is for numeric comparison not string

the easiest way is the force the value to either all caps or lowercase letters, but that may not be the baest way if you need the data to remain in its current condition.


$a =~ tr/a-z/A-Z/; #change all letters to CAPS
$a =~ tr/A-Z/a-z/; #change all letters to lower case

the easiest way? I would think using uc() or lc() would be the easiest. Maybe not...

 

[qwicker]

thanks, i just did $abs = "\L$abs\E";

if that's what you're doing, surely [tt]$abs = lc($abs);[/tt] is better on all fronts
