使用json_encode和PHP处理base64编码图像

问题描述：

My PHP class returns a small base64 encoded image, link this:

class Service
{

  function getLogo()
  {
    $image = "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4c
             QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwA";

    return 'data:image/png;base64,' . $image;
  }

}

Returning the image using json_encode will add after each line of $image:

$service = new Service();
$response = array('name' => $service->getName(), 'logo' => $service->getLogo());
header('Content-type: application/json');
echo json_encode($response);

How to handle it correctly?

我的PHP类返回一个小的base64编码图像，链接： p>

   class Service 
 {
 
函数getLogo（）
 {
 $ image =“iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8 / 9hAAAAAXNSR0IArs4c 
 QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAAAAAAAgAgAgAAHAwA”; 
 
返回'data：image / png; base64，'。  $ image; 
} 
 
} 
  code>  pre> 
 
 使用 json_encode  code>返回图像将添加 
  code  >在每行 $ image  code>之后： p> 
 
 
  $ service = new Service（）; 
 $ response = array（'name'=＆gt;  $ service-＆gt; getName（），'logo'=＆gt; $ service-＆gt; getLogo（））; 
header（'Content-type：application / json'）; 
echo json_encode（$ response）;

答

You've mangled your base64 data by splitting it across two lines. it should be

function getLogo() {
    $image = "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4cQAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwA";

    return 'data:image/png;base64,' . $image;
}

with no line breaks.

The answer is given by Marc B. This is just a comment. If code formatting really is that important to you that you can't tolerate long lines (why?), you could always format the PHP thus:

class Service
{

  function getLogo()
  {
    $image  = 'iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4c';
    $image .= 'QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwA';

    return 'data:image/png;base64,' . $image;
  }

}
