StartsWith ViewHelper checks if the subject string starts with a specified string.
This ViewHelper implements an if/else condition.

## Examples {#examples}

### Render the body if "myString" starts with "Hello" {#render-the-body-if-mystring-starts-with-hello}

```php
<f:variable name="myString" value="Hello, World!" />
<f:startsWith search="Hello" subject="{myString}">This will be rendered if variable "myString" starts with "Hello"</f:startsWith>

```

Output:

```php
This will be rendered if variable "myString" starts with "Hello"

```

### A more complex example with inline notation {#a-more-complex-example-with-inline-notation}

```php
<f:variable name="condition" value="{false}" />
<f:variable name="myString" value="Hello, World!" />

<f:if condition="{condition} || {f:startsWith(search: 'Hello', subject: myString)}">
It Works!
</f:if>

```

Output:

```php
It Works!
```
