)) (Her görüntü indir) file_get_contents Aşağıdaki kodu kullanarak ortalama 8-15 saniye alır .....
Ben file_get_contents bir bağlam kullanmak istemiyorsanız () sonra görüntü indirme bir saniyeden daha azdır.
Ben $ seçmesi değiştirirseniz, aşağıda sonra ben 2.500 imagesx işlemek için appox 13 saniye sürer bir bağlam olmadan file_get_contents () aynı performansı olsun.
