如代码GD生成了图片$im:
<code> public function generateCode(){ $w = 50; $h = 20; $this->load->config('common'); $common_config = $this->config->item('common'); $pic_verify_code = $common_config['pic_verify_code']; $code = func::getRandCode($pic_verify_code); //创建图片，定义颜色值 $im = imagecreate($w, $h); $black = imagecolorallocate($im,90,90,90); $gray = imagecolorallocate($im, 189,252,201); $bgcolor = imagecolorallocate($im, 255, 255, 255); //填充背景 imagefill($im, 0, 0, $gray); //画边框 imagerectangle($im, 0, 0, $w-1, $h-1, $black); //随机绘制两条虚线，起干扰作用 $style = array ($black,$black,$black,$black,$black, $gray,$gray,$gray,$gray,$gray ); imagesetstyle($im, $style); $y1 = rand(0, $h); $y2 = rand(0, $h); $y3 = rand(0, $h); $y4 = rand(0, $h); imageline($im, 0, $y1, $w, $y3, IMG_COLOR_STYLED); imageline($im, 0, $y2, $w, $y4, IMG_COLOR_STYLED); //在画布上随机生成大量黑点，起干扰作用 for ($i = 0; $i < 80; $i++) { imagesetpixel($im, rand(0, $w), rand(0, $h), $black); } //将数字随机显示在画布上,字符的水平间距和位置都按一定波动范围随机生成 $strx = rand(3, 8); for ($i = 0; $i < $pic_verify_code; $i++) { $strpos = rand(1, 6); imagestring($im, 5, $strx, $strpos, substr($code, $i, 1), $black); $strx += rand(8, 12); }</code>
那么问题来了，怎么把这个图片存到我的服务器上面呢?

write to file ,e. fwite()
<code>imagepng($im,'pic.png');</code>
验证码直接发给客户端不就好了，保存起来干嘛；
xxx.php直接：
imagepng($im);
