Online Lower Case Converter

Is there a way to convert a string from uppercase, or even part uppercase to lowercase?

E.g. Kilometers --> kilometers.

I have a simple parser that parse a csv file and return me an array indexed by the names of the cells in the header row, here is my code :

$file = file(public_path() .'/screens/'. $file, FILE_SKIP_EMPTY_LINES);$csv = array_map("str_getcsv", $file, array_fill(0, count($file), ';'));$keys = array_shift($csv);$response = (object)array();foreach ($csv as $i => $row) {  // Combine headers with values  $csv[$i] = array_combine($keys, $row);  $wellName = $csv[$i]["Well"];  $response->{$wellName} = array_combine($keys, $row);}return $response;

My problem is that in my csvfiles sometimes the headers have an uppercase at the beggining or in the word, but I don't know where I am supposed to do my strtolower in my parsing function, I want that only the headers are in lower cases.

I need some help with my script.

The full script can be found here

The portion of the script I need help with is this:

If (Len(strTitle) > 3) Then    arrStr = Split(strTitle," ")    For i=0 To UBound(arrStr)        word = LCase(Trim(arrStr(i)))        word = Replace(word, Mid(word, 1, 1), UCase(Mid(word, 1, 1)), 1, 1)        strTitleCon = strTitleCon & word & " "    NextEnd If

In our AD, everything is written in uppercase which is why I need to make it title case. However, this doesn't work if it's for title's like "QC Technician" or "HR Manager".

How can I go about doing that with the current script that I have?

I am trying to make a program that stores a string in a variable called input.

With this input variable, I am then trying to convert it to an array, and then test with a for loop whether each character in the array is lowerCase or not. How can I achieve this?

Here is how far I have gotten:

var input = "The quick BroWn fOX jumpS Over tHe lazY DOg"var inputArray = Array(input)for character in inputArray {    /*    if character is lower case {        make it uppercase    } else {        make it lowercase    }    */}

I have a string, "abc". How would a program look like (if possible, in Java) who permute the String?

For example:

abcABCAbcaBcabCABcabCAbC
