这是我的验证码中的代码:

    {
        /* list all possible characters, similar looking characters and vowels have been removed */
        $possible = '23456789bcdfghjkmnpqrstvwxyz';
        $code = '';
        $i = 0;
        while ($i < $characters)

        imagejpeg($image);
        imagedestroy($image);
        $session->set('osm_security_code', $code);
    }
}

此处是HTML:

<div style="position:relative">
                <input type="text" class="inputbox input-mini" value="" size="8" name="security_code">
                    <img src="/rejestracja-enterprise-kwartalnie?task=show_captcha_image" title="Please enter the code you see in the image into Security code textbox" align="middle" id="captcha_image">
                    <a class="osm_reload" href="javascript:reloadCaptcha();"></a>
                                        </div>

推荐答案

即图像.您只是没有告诉浏览器它是什么，您的浏览器将数据解释为文本.设置标题以告诉您的浏览器将数据解释为图像:

That is the image. You're just not telling your browser that it is, your browser interprets the data as text. Set a header to tell your browser to interpret the data as image:

header('Content-Type: image/jpeg');

图像数据将必须是页面上唯一的输出，之前或之后必须没有其他HTML或文本.

The image data will have to be the only thing output on the page, no other HTML or text before or after it.

引用链接: php imagejpeg()

尝试

ob_start();
header( "Content-type: image/jpeg" );
imagejpeg( $image, NULL, 100 );
imagedestroy( $image );
$i = ob_get_clean();

echo "<img src='data:image/jpeg;base64," . base64_encode( $i )."'>"; //saviour line!
