属性或数组-PHP

Question

I need to find out, if a function parameter in my php-script is a regular string attribute or an array.

How would I do that?

if(gettype($array) == "string"){return $array;}

doesn't work.

is there an error in this line? I'm new to php.

Technically there are bunch of options. It might be safer to specifically check for both desired. PHP has methods to check for each of its types.

if(is_array($array)) {
  // array
}
elseif( is_string($array)) {
  // string
}
elseif( is_object($array)) {
  // object
}
// could also do is_float, is_number, is_boolean, is_resource
