# Captcha

It's simply an old-school captcha app.



## Requirements

- PHP 5.6 or higher

- PHP GD Extension

## Installation

```

composer require muhammetsafak/captcha:dev-main

```

or download and include the file `src/Captcha.php`.

## 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

```

$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`

```php

require_once __DIR__ . '/src/Captcha.php';

$config = array(

    'width'         => 180,

    'height'        => 50,

    'length'        => 6

);

$captcha = new \MuhammetSafak\Captcha\Captcha($config);

$captcha->create();

```

```html

    


    

     


    Refresh

    


    

    

    function captcha_refresh()

    {

        img = document.getElementById("captcha");

        img.src = '../src/image-captcha.php';

    }

```

A simple validation example is as follows.

```php

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.';

    }

}

```
