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         


        

Answer 1

$stringWithDash = 'Pending-Seller-Confirmation'; $camelize = str_replace('-', '', ucwords($stringWithDash, '-')); echo $camelize; output: PendingSellerConfirmation

ucwords second(optional) parameter helps in identify a separator to camelize the string. str_replace is used to finalize the output by removing the separator.

Answer 2

Here is a small helper function using a functional array_reduce approach. Requires at least PHP 7.0

private function toCamelCase(string $stringToTransform, string $delimiter = '_'): string
{
    return array_reduce(
        explode($delimiter, $stringToTransform),
        function ($carry, string $part): string {
            return $carry === null ? $part: $carry . ucfirst($part);
        }
    );
}

Answer 3

I would probably use preg_replace_callback(), like this:

function dashesToCamelCase($string, $capitalizeFirstCharacter = false) {
  return preg_replace_callback("/-[a-zA-Z]/", 'removeDashAndCapitalize', $string);
}

function removeDashAndCapitalize($matches) {
  return strtoupper($matches[0][1]);
}

Answer 4

function camelCase($text) {
    return array_reduce(
         explode('-', strtolower($text)),
         function ($carry, $value) {
             $carry .= ucfirst($value);
             return $carry;
         },
         '');
}

Obviously, if another delimiter than '-', e.g. '_', is to be matched too, then this won't work, then a preg_replace could convert all (consecutive) delimiters to '-' in $text first...

Answer 5

This is simpler :

$string = preg_replace( '/-(.?)/e',"strtoupper('$1')", strtolower( $string ) );

Answer 6

One liner, PHP >= 5.3:

$camelCase = lcfirst(join(array_map('ucfirst', explode('-', $url))));
