Errors And Exception
- The link() function does not work on remote files as the file to be examined must be accessible via the server’s filesystem.
- The link created by the link() function is not an HTML link, but a link in the filesystem..
- In linux, hardlinking to a directory is not permitted.
Examples:
Input : $targetfile = 'gfg.txt.';
$linkname = 'gfglink';
link($targetfile, $linkname);
Output : 1
Input : $targetfile = 'gfg.txt.';
$linkname = 'gfglink';
if(!link($targetfile, $linkname))
{
echo('Link has been created!');
}
else
{
echo('Link cannot be created!');
}
