Documentation
1. Create new Captcha
$captcha = new SimpleCaptcha();
If no parameters are passed the captcha code will be automatically generated with a length of 5 numeric characters.
But it is possible to pass two parameters. The first is a string with the captcha code (maximum length of 16 characters), the second is a boolean to generate random colors if true.
$captcha = new SimpleCaptcha("H@ck3R'D_C0@r1", true);
2. Get the captcha code
$captcha->getKey();
3. Get the captcha image
<img src="<?php echo $captcha->getImg() ?>" />
Example
A simple usage example.
<?php require __DIR__ . '/../vendor/autoload.php'; use WilliamSampaio\SimpleCaptcha\SimpleCaptcha; session_start(); $captcha = new SimpleCaptcha(); if(isset($_POST['captcha'])){ if($_POST['captcha'] == $_SESSION['captcha']->getKey()){ echo "<h1 style='color:green;'>Captcha valid! (".$_POST['captcha'] ."=". $_SESSION['captcha']->getKey().")</h1>"; }else{ echo "<h1 style='color:red;'>Captcha invalid! (".$_POST['captcha'] ."=". $_SESSION['captcha']->getKey().")</h1>"; } } $_SESSION['captcha'] = $captcha; ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <form method="post"> <img src="<?= $captcha->getImg() ?>"/> <br> <input type="text" name="captcha" id="captcha"> <hr> <input type="submit" value="Check"> </form> </body> </html>
