[](#usage)

The file `src/image-captcha.php` simply generates and presents a captcha for you. You can edit this file for a custom configuration or create your own.

### Configuration

[](#configuration)

```
$configs = array(
    'width'         => 200, // Width of captcha image to be created
    'height'        => 70, // Height of captcha image to be created
    'length'        => 7, // The number of characters to be found in the captcha image.
    'font'          => __DIR__ . '/src/AHGBold.ttf', // Defines the font of the captcha characters.
    'size'          => 18 // Defines the size of captcha characters.
);

```

To create a captcha image; `image-captcha.php`

```
require_once __DIR__ . '/src/Captcha.php';
$config = array(
    'width'         => 180,
    'height'        => 50,
    'length'        => 6
);
$captcha = new \MuhammetSafak\Captcha\Captcha($config);
$captcha->create();
```

```

    Refresh

    function captcha_refresh()
    {
        img = document.getElementById("captcha");
        img.src = '../src/image-captcha.php';
    }

```

A simple validation example is as follows.

```
require_once __DIR__ . '/src/Captcha.php';
$captcha = new \MuhammetSafak\Captcha\Captcha();
if(isset($_POST)){
    if($captcha->verify($_POST['areYouBot'])){
        // Success
        // ...process
    }else{
        // Error
        echo 'Enter the characters in the picture correctly.';
    }
}
```
