note 123816 added to function.filesize

I have a PDF file on my Google drive, and I need to calculate its size in PHP through its shareable link. Is there a function in PHP can do this? Let’s say something like this: function calcsize(file_link) echo (“size is:” + size ) Thank you in advance. ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.142 (proxied: 5.0.114.116) ---- Manual Page -- http://php.net/manual/en/function.filesize.php Edit -- https://master.php.net/note/edit/123816 Del: integrated -- https://master.php.net/note/delete/123816/integrated Del: useless -- https://master.php.net/note/delete/123816/useless Del: bad code -- https://master.php.net/note/delete/123816/bad+code Del: spam -- https://master.php.net/note/delete/123816/spam Del: non-english -- https://master.php.net/note/delete/123816/non-english Del: in docs -- https://master.php.net/note/delete/123816/in+docs Del: other reasons-- https://master.php.net/note/delete/123816 Reject -- https://master.php.net/note/reject/123816 Search -- https://master.php.net/manage/user-notes.php
