从url2png获取屏幕截图并保存到FTP

Question

I am using url2png to get screenshots from pages. However, instead of asking the image every time, I want to save it onto an external server via FTP.

My first approach was to use:

$image = fopen($src,"r");

And then an ftp_fput. But as url2png may take about 5 secs to get the screenshot, the ftp_fput uploads an empty file.

Do I need to save the file locally first? or is there a workaround?

Thanks!

Found a solution using this question: Using file_get_contents and ftp_put

$fp = fopen('php://temp', 'r+');
fputs($fp, file_get_contents($src));
rewind($fp);
