php 将base64转换成图片并保存 阿星小栈

 public function setBaseToImg(Request $request){
        $base64_image_content = $request->get('imgBase64','imgBase64');
        //匹配出图片的格式
        $preg = preg_match('/^(data:s*image/(w+);base64,)/', $base64_image_content, $result);
        if ($preg){
            $type = $result[2];
            $new_file = public_path('/html5/blessing/baseImg/');
            if(!file_exists($new_file))
            {
                //检查是否有该文件夹，如果没有就创建，并给予最高权限
                mkdir($new_file, 0700);
            }
            $new_file = $new_file.time().uniqid().".{$type}";
            if (file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64_image_content)))){
                 return $new_file;
            }else{
                 return false;
            }
        }
    }

此处我用了Laravel框架自带方法，下面是原始方法，都可用

  public function setBaseToImg(){
        $base64_image_content = $_POST['imgBase64'];
        //匹配出图片的格式
        $preg = preg_match('/^(data:s*image/(w+);base64,)/', $base64_image_content, $result);
        if ($preg){
            $type = $result[2];
            $new_file = '/html5/blessing/baseImg/';
            if(!file_exists($new_file))
            {
                //检查是否有该文件夹，如果没有就创建，并给予最高权限
                mkdir($new_file, 0700);

            }
            $new_file = $new_file.time().uniqid().".{$type}";
            if (file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64_image_content)))){
                 return $new_file;
            }else{
                 return false;
            }
        }
    }
