# Placeholder Types

When creating routes with placeholders, we can specify the type of data in the placeholder that is to be expected. Currently this framework supports `int, string and path` types. Below we will see how to use these different types with placeholders.

To specify the type of placeholder, we write it in the format `name:type` in the route.

```php
Router::add_route("GET", '/echo/{name:string}', [Controller::class, 'index']);
```

### Integers

To specify integer placeholders in the route we use the type `int` .

```php
Router::add_route('GET', '/echo/{id:int}', [Controller::class, 'index']);
```

In the above line, we created a route `/echo/{id:int}` which would basically capture the number that comes after `/echo/` . It will only match integers and hence would cause error handler to be called if we use string or path in place of integer.

### Strings

To specify the placeholders as strings, we just use the type `string`.

```php
Router::add_route("GET", '/echo/{name:string}', [Controller::class, 'index']);
```

Now, placeholder will capture a string that comes after `/echo/`

### Path

Now, lets say i want to capture an entire Path which comes at the placeholders place. `path` type is used for this and it captures a path.

```php
Router::add_route('GET', '/echo/{way:path}', [Cont::class, 'index']);
```

So, now if a user tries to visit `/echo/shoaib/wani` the `way` placeholder will contain `shoaib/wani`.
