Re: Detection of missing links

Hello DXTrim

I am working with a colleague who may well write the 'detailed information
pages' (DIPs) on web pages on his computer whilst my searchable index is
kept on my computer. (I know this sounds a bit daft but there are politics,
ownership and cgi issues to be resolved!)

So if the DIPs were on his PC then I would access them from the 'More' link
as a typical URL.

If commonsense prevails, the DIPs would be on my website so it would be
perhaps just a question of opening an htm file.
Now I am very new to PHP and I was casting around for a method to check the
existence of a file. I was thinking of using the fopen function - something
like

$openfile = fopen($filename, 'r');
if (!$openfile) {
... suppress the 'More' link ...
}
unlink($filename);

I have included the 'unlink' to close the file because this code would be
actioned repeatedly by the loop which generates the table.

But I could not get this to work.

Any ideas - most welcome
