Error message trying to include a file

Hi php-general,

I have an array filled with urls of javascript files and then I
include them one by one in a loop.

for( $i = 0 ; $i < sizeof($this->page->javascript) ; $i++ ){

include($this->page->javascript[$i]);
//This line above is line 52 shown on error warning
}

When I had only two files to include it worked. Now I added a third
and I get following error message:

Notice: Undefined offset: 2 in /usr/local/www/ViewPageClass.php on line 52

Warning: writehead() [function.writehead]:
Failed opening '' for inclusion (include_path='.:/usr/local/lib/php')
in /usr/local/www/ViewPageClass.php on line 52

I don't really know what to do,the function writehead doesn't seem to
exist... the javascript file is
http://pajhome.org.uk/crypt/md5/md5.js. I suppose it's free of
errors...

what does print_r($this->page->javascript) yield?

you'd be better off with a loop like:
foreach($this->page->javascript as $file_to_include) {
include($file_to_include);
}

Probably

include($this->page->javascript[$i]);

Is the problem. There's this thing in PHP that you can't do this thing with
referencing to an object property from within an other object. Or whatever
to call that. Sounds silly and stupid, but it bullies me too. Try this:

$Page =& $this->page;
foreach($Page->javascript as $File) include($File);

or this (if you care about memory usage):

$Page =& $this->page;
foreach(array_keys($Page->javascript) as $i)
include($Page->javascript[$i]);

Because php doesn't do reference thingies in a foreach loop, sadly.
