create_captcha()

create_captcha([$data = ''[, $img_path = ''[, $img_url = ''[, $font_path = '']]]])

Takes an array of information to generate the CAPTCHA as input and creates the image to your specifications, returning an array of associative data about the image.

array(
        'image' => IMAGE TAG
        'time'  => TIMESTAMP (in microtime)
        'word'  => CAPTCHA WORD
)

The image is the actual image tag:

<img src="http://example.com/captcha/12345.jpg" width="140" height="50" />

The time is the micro timestamp used as the image name without the file extension. It will be a number like this: 1139612155.3422

The word is the word that appears in the captcha image, which if not supplied to the function, will be a random string.
