Convert Dashes to CamelCase in PHP

Question

Can someone help me complete this PHP function? I want to take a string like this: \'this-is-a-string\' and convert it to this: \'thisIsAString\':

function d

This function is similar to @Svens's function

function toCamelCase($str, $first_letter = false) {
    $arr = explode('-', $str);
    foreach ($arr as $key => $value) {
        $cond = $key > 0 || $first_letter;
        $arr[$key] = $cond ? ucfirst($value) : $value;
    }
    return implode('', $arr);
}

But clearer, (i think :D) and with the optional parameter to capitalize the first letter or not.

Usage:

$dashes = 'function-test-camel-case';
$ex1 = toCamelCase($dashes);
$ex2 = toCamelCase($dashes, true);

var_dump($ex1);
//string(21) "functionTestCamelCase"
var_dump($ex2);
//string(21) "FunctionTestCamelCase"
