如何獲取圖像的大小？

Question

我有這個數組想要獲取圖像的大小：

$main_image = $product->images()->where('main_image', 1)->first();

if($main_image){
    $url = asset('uploads/products/'. $main_image['image']);

    $image[] = [
        "name"  => $main_image->image,
        "type"  => FileUploader::mime_content_type($main_image->image_path),

        "size"  => filesize($url),

        "file"  => $main_image->image_path,
        "local" => $main_image->image_path,
    ];
}

我收到此錯誤：

filesize(): stat failed for http://myapp.test/uploads/products/83QhiRFarGpV.jpeg 

甚至我的圖像也存在於文件夾中！：

我嘗試了所有在這個選項一個在所有但仍同樣的錯誤！

Answer 1

您的代碼正在使用asset()生成$url ：

http://myapp.test/uploads/products/83QhiRFarGpV.jpeg

filesize()函數適用於本地文件，而不是 URL。

filesize($main_image->image_path)應該可以工作，因為您在上面的行中使用它來獲取文件類型。

你可能還有另一個問題

   "file"  => $main_image->image_path,
   "local" => $main_image->image_path,

您可能希望文件改為$url 。
