Question

我有这个工作，然后突然改变了一些东西，我的php验证码不断失败。我觉得这可能是服务器方面的问题，但我找不到任何错误。

我正在使用

https://www.phpcaptcha.org/
https://github.com/dapphp/securimage

我正在网站的根级别对此进行测试。

<?php

session_start();

require_once('securimage/securimage.php');

?>

<form class="" method="post" action="" enctype="multipart/form-data" id="captcha">
    <?php
    $options = array();
    $options['namespace'] = 'captcha';
    $options['input_id'] = 'captcha_code';
    echo Securimage::getCaptchaHtml($options, Securimage::HTML_IMG);
    echo Securimage::getCaptchaHtml($options, Securimage::HTML_ICON_REFRESH);
    echo Securimage::getCaptchaHTML($options, Securimage::HTML_INPUT);
    ?>

    <input type="submit" value="submit">
</form>


<?php

if($_SERVER['REQUEST_METHOD'] == 'POST')
    { 

        $captcha_code = isset($_POST['captcha_code']) ? $_POST['captcha_code'] : null;

        $image = new Securimage();

        var_dump($_SESSION);

        if($image->check($captcha_code) == true) 
            {
                echo "Captcha was good!"; 
            } 
        else 
            {
                echo "Captcha did NOT match!";
            }

    }

?>

验证码$ SESSSION []已正确设置。

array(4) 
    { 
        ["securimage_code_disp"]=> array(1) 
            { 
                ["captcha"]=> string(6) "LG2BE2" 
            } 
        ["securimage_code_value"]=> array(1) 
            { 
                ["captcha"]=> string(6) "lg2be2" 
            } 
        ["securimage_code_ctime"]=> array(1) 
            { 
                ["captcha"]=> int(1457447465) 
            } 
        ["securimage_code_audio"]=> array(1) 
            { 
                ["captcha"]=> NULL 
            } 
    }

但无论我尝试什么，if条件总是失败。返回False。

if($image->check($captcha_code) == true) 
            {
                echo "Captcha was good!"; 
            } 
        else 
            {
                echo "Captcha did NOT match!";
            }

除验证部分外，一切正常。它拒绝工作。

PHP Captcha拒绝验证
