del.icio.us links now cron'd

I finally got the impetus to cron my del.icio.us links over on the right. The format can be improved, but I'm in a hurry, so I'll do that later.

Hmm... might as well share the source. First, the cron:


<?php
$location = 'http://del.icio.us/html/keith?extended=body';
if(!$file = @file_get_contents($location)){
    if(!$file = @file_get_contents($location)){ #try one more time
        die("Couldn't get $location");
    }
}
$f = @fopen('/home/keith/kbdcms/Data/delicious.html','w') or die("Couldn't open file");
fwrite($f,$file);
fclose($f);
?>

That's currently set to run every 90 minutes. Next, the part of my template which fetches the thing:


<h2 id="delicious">del.icio.us links:</h2>
<?php readfile('/.../delicious.html');?>

Piece of cake. Someone asked me the other day what's good about PHP, why I'd use it, etc. This is an example of it. If I had PHP5, I could have done away with fopen(), etc. and just used file_put_contents() and saved two lines.

Update: Updated the source a bit. Incidentally, I'm wondering if I've been confused about PHP's scoping behavior.

Or you could have done include('http://del.icio.us/html/keith?extended=body');

That would be sweet!

Sorry, I shouldn't even say such things. Including remote URLs (whose contents are then parsed, I believe?) is bad. Doing that on every page load is pretty bad too.

Well, I could do something like:

echo file_get_contents('http://del.icio.us/html/keith?extended=body');

which wouldn't interpret the contents as PHP. Yes, include()ing remotely is bad.

But, of course, I can't be hitting del.icio.us on every page request. Not only is it very rude, but it would slow my site down as well.

Feel free to post a comment below. Please see my comment policy.

Formatting Rules (No HTML):

**bold**, *italic*, _underlined_, --strikeout--
"text"="url" creates a link, and URLs are auto-highlighted
Blockquote: Like e-mail, begin paragraph with > (greater-than sign)
Lists: begin paragraph with *,-, or + (unordered), or # (ordered)
Code block: ?!code:language=perl|php|sql|javascript|etc.{\n}...{\n}?!/code
