如何在Codeigniter中将BASE64转换为图像？

Question

Codeigniter代码：

$filedata = explode(',', $this->input->post('lostimage1'));
$pos  = strpos($this->input->post('lostimage1'), ';');
$type = explode(':', substr($this->input->post('lostimage1'), 0, $pos))[1];
$type = '.'.$type;
$type = str_replace('image/', '', $type);
$img1 = $img['img'].''.$type;
write_file('./uploads/'.$data['pet_hidenum'].'/'.$img1, $filedata[1]);

我的代码工作正常。当我从服务器下载图像并在paint或chrome中打开图像时，它显示错误无效位图如何解决此错误？

尝试以下几点：

$image = imagecreatefromjpeg($filename);
echo '<img src="data:image/jpeg;base64,'.base64_encode(imagejpeg($image)).'" />';
