        // Handle NULL values
    }
    // Override other Accept methods for different types (e.g., AcceptString, AcceptArray)
}

// Assuming 'value' is an instance of PhpValue
value.Accept( new MyVisitor() ); // Traverses through the value, arrays and objects
```

### Target .NET Standard 2.0 for Library Projects

Source: https://docs.peachpie.io/scenarios/beginner/full-net-framework

Sets the project to target .NET Standard 2.0, maximizing compatibility with other .NET projects. This is the recommended approach when compiling a library.

```xml
<TargetFramework>netstandard2.0</TargetFramework>
```

### Insert PHP Script in Razor Page (Razor/C#)

Source: https://docs.peachpie.io/scenarios/blazor/inserting-php-scripts

This Razor component demonstrates how to use the PhpScriptProvider to execute and render a specific PHP script ('index.php'). It includes placeholders for 'Navigating' and 'NotFound' states, allowing for custom UI feedback during script loading or if the script is not found.

```razor
@page "/index.php"
@using Peachpie.Blazor

<!--Other Blazor content (optional)-->

<PhpScriptProvider Type="@PhpScriptProviderType.Script" ScriptName="index.php">
    <Navigating>
        <p>Navigating</p>
    </Navigating>
    <NotFound>
        <p>Script not found</p>
    </NotFound>
</PhpScriptProvider>

<!--Other Blazor content (optional)-->

```

### Add Peachpie.AspNetCore.Mvc NuGet Package

Source: https://docs.peachpie.io/scenarios/intermediate/razor

Adds the Peachpie.AspNetCore.Mvc NuGet package as a dependency. This package provides the necessary extensions for integrating PHP with ASP.NET Core MVC.

```xml
<PackageReference Include="Peachpie.AspNetCore.Mvc" Version="1.1.11" />

```

### PHP Application Including and Using PHP Library

Source: https://docs.peachpie.io/scenarios/beginner/reference-php-project

This code illustrates how a PHP application can include and utilize a PHP library class. It uses `require_once` to include the library file and then instantiates `Library\Class1` to call the `encode` method, echoing the result. This approach is common when the library is part of another PHP project.

```php
<?php

require_once './class1.php';

$c = new Library\Class1;
echo $c->encode('Hello World!');

?>
```

### VS Code Debugger Configuration for PeachPie

Source: https://docs.peachpie.io/scenarios/intermediate/debugging-peachpie

Configuration for VS Code's `launch.json` to enable debugging of PeachPie. It disables 'Just My Code' and specifies search paths for debug symbols.

```json
"justMyCode": false,
"symbolOptions": {
  "searchPaths":["C:\\peachpie\\src\\Peachpie.App\\bin\\Debug\\netstandard2.0"]
}

```

### Link Static Files from Another Project in Blazor

Source: https://docs.peachpie.io/scenarios/blazor/inserting-php-scripts

Configures the Blazor project's .csproj file to link static files from another project's wwwroot folder. Uses the 'None' item type with 'Link' and 'CopyToOutputDirectory' properties to include files while maintaining project structure.

```xml
...
<ItemGroup>
    <None Include="..\..\PHPScripts\wwwroot\**\*">
        <Link>wwwroot\%(RecursiveDir)/%(FileName)%(Extension)</Link>
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
</ItemGroup>
...

```

### C# Application Calling PHP Library Method

Source: https://docs.peachpie.io/scenarios/beginner/reference-php-project

This snippet demonstrates how to instantiate a PHP class and call its methods from a C# application after referencing the PHP library. It highlights the use of `Library.Class1` and its `encode` method, with Console output for the result. Implicit type conversions between PHP and C# are managed by the library.

```csharp
static void Main(string[] args)
{
    // instantiate PHP class
    var class1 = new Library.Class1();
    // call PHP method with an argument
    string encoded = class1.encode("Hello World!");
    // output the result
    Console.WriteLine(encoded);
}
```

### Call PHP Function from JavaScript

Source: https://docs.peachpie.io/scenarios/blazor/php-js-interoperability

This example demonstrates calling a PHP function from JavaScript. A button click triggers the `window.php.callPHP` method, which sends the function name and parameters (as a JSON structure) to the PHP environment. The PHP function `CallPHP` then decodes the JSON and processes the data. This requires an instance of `PhpScriptProvider` or `PhpComponent` to be available.

```html+php
<p>Click and look at console output</p>
<button onclick="window.php.callPHP('CallPHP', { name : 'Bon', surname: 'Jovi'});">PHP</button>
<?php

function CallPHP($data)
{
    $json = json_decode($data); 

    echo "Hello ". $json->name . " " . $json->surname .  " from PHP\n";
}
?>
```

--------------------------------

### Create Empty CLI Context

Source: https://docs.peachpie.io/api/ref/context

Creates a new Command Line Interface (CLI) context without a specified output stream. It's crucial to set the WorkingDirectory and RootPath properties after creation for proper script resolution.

```C#
Peachpie.Runtime.Context context = Peachpie.Runtime.Context.CreateEmpty();
context.WorkingDirectory = "/path/to/working/dir";
context.RootPath = "/path/to/root";
```
