Symlinks, short for symbolic links, are basically shortcuts to individual files or folders. One of the advantages of a symlink is that it can cross filesystems, as it references abstract filenames/directories and not physical locations.
There is a number of ways to create a symlink
1) Remove storage folder in public_html/public/storage
2) Create a php file for example symlink.php in public_html folder
3) Add codes to symlink.php file
$targetFolder = $_SERVER['DOCUMENT_ROOT'].'/storage/app/public';
$linkFolder = $_SERVER['DOCUMENT_ROOT'].'/public/storage';
symlink($targetFolder,$linkFolder);
echo 'Symlink process successfully completed';4) Go to web site example.com/symlink.php
That is all...
