# variant_get_type

(PHP 5, PHP 7)

variant_get_type — Returns the type of a variant object

### 说明

variant_get_type ( variant `$variant` ) : int

Returns the type of a variant object.

### 参数

`variant`

  The variant object.

### 返回值

This function returns an integer value that indicates the type of `variant`, which can be an instance of COM, DOTNET or VARIANT classes. The return value can be compared to one of the `VT_XXX` constants.

The return value for COM and DOTNET objects will usually be `VT_DISPATCH`; the only reason this function works for those classes is because COM and DOTNET are descendants of VARIANT.

In PHP versions prior to 5, you could obtain this information from instances of the VARIANT class ONLY, by reading a fake `type` property. See the VARIANT class for more information on this.
