Let's say I've got a PHP function foo:
function foo($firstName = 'john', $lastName = 'doe') {
echo $firstName . " " . $lastName;
}
// foo(); --> john doe
Is there any way to specify only the second optional parameter?
Example:
foo($lastName='smith'); // output: john smith
No, this isn't possible, as stated on the Function arguments manual page:
The default value must be a constant expression, not (for example) a variable, a class member or a function call.
Instead you could either simply pass in null as the default and update this within your function...
function actionOne($id=null) {
$id = isset($id) ? $id : $_GET['ID'];
....
}
...or (better still), simply provide $_GET['ID'] as the argument value when you don't have a specific ID to pass in. (i.e.: Handle this outside the function.)
Change your sub and add ByVal
Public Sub CalculateMe(Optional ByVal strA As String, Optional ByVal strB As String)
There's no other way to do it in a ServletFilter other than trying to parse the URI yourself, but you can access the path parameters if you decide to use a JAX-RS request filter:
@Provider
public class PathParamterFilter implements ContainerRequestFilter {
@Override
public void filter(ContainerRequestContext request) throws IOException {
MultivaluedMap<String, String> pathParameters = request.getUriInfo().getPathParameters();
pathParameters.get("status");
....
}
}
SpreadsheetGear provides no option to specify the encoding of a CSV file, or option to specify what delimiter is used for a given text-based data file. If you have a CSV encoded with UTF, you would need to build your own routine that reads and handles this file accordingly, then manually insert that data into your worksheet cell-by-cell.
PHP does not support named parameters for functions per se. However, there are some ways to get around this:
