[英]How to save save user's facebook profile picture to my domain/website data using php
i want to save the user's profile picture of facebook to my disk, it is more like scrapping user's profile picture db when they registered first.' 我想将用户的个人资料图片保存到我的磁盘上,这更像是在用户首次注册时删除用户的个人资料图片。
for example here is the url. 例如,这里是网址。
https://graph.facebook.com/ {id}/picture https://graph.facebook.com/ {id} / picture
i want to save it under a specific directory. 我想将它保存在特定目录下。 also, if there is not picture, i want to download the default placeholder as well, which is GIF.
另外,如果没有图片,我也想下载默认占位符,即GIF。 the above url is actually having a placeholder only.
上面的url实际上只有一个占位符。
i am beginner in php, please explain me in detail. 我是php的初学者,请详细解释我。
