[RESOLVED] array help (extract)

guest

What I am trying to do is a 'network sites' links where all the network sites are in an array and after each network site there is a ',' except the last one (because it is the last item of the list) so say the current site was google.com

$all_sites = array('google.com','exaple.com','test.info','site.com','text.com');

what i want to do is
if $_SERVER['HTTP_HOST'] = $array['google.com'] then to take google.com out of the array so there are only 4 other sites left in the array.. I tried doing it like this

function network_sites(){
	global $all_sites;
	global $site_url;
	$number_of_links = 4;
	shuffle($all_sites);
	for ($i=0; $i<$number_of_links; $i++) {
	$capitalize = ucfirst($all_sites[$i]);
	if ($all_sites[$i] != $site_url){
	$last_site = $number_of_links - 1;
		if ($last_site == $i){
			echo '<a href="http://'.$all_sites[$i].'/">'.$capitalize.'</a>';
		}else{
			echo '<a href="http://'.$all_sites[$i].'/">'.$capitalize.'</a>, ';
			}
		}
	}
}

but sometimes the last site has a comma in the end.. and it displays only 3 network sites (when its supposed to show 4) most of the time because if ($all_sites[$i] != $site_url) is being true and just doing nothing.
Exaple.com, Test.info, Site.com,

I think it would be easier and faster to just tackle the exporting before the function is needed but I couldn't find anything on how to completely take out a value of an array so it doesn't exist any more.

Thanks

Have you looked at [man]unset[/man]? You can use it to unset a key in an array. Unfortunately your network names aren't keys but values. But then you can use something on the lines of:

unset($all_sites[array_search("test.info")]);

thanks and fixed a small error

unset($all_sites[array_search("test.info", $all_sites)]);

for any other people out there, it cant be

$all_sites = array('google.com','exaple.com','test.info','site.com','text.com');
$all_sites = unset($all_sites[array_search("test.info", $all_sites)]);

it just has to be unset alone w/ out the $all_sites thing. Thx for the help

So you have an array of domain names, and you want to list them in some random order, separated by commas (except for one that may already have been supplied)?

function network_sites()
{
	// Ideal candidates for function parameters
	global $all_sites, $site_url;
	$number_of_links = 4;
	// Use $all_sites instead of $candidate_sites
	// if you really do want to remove $site_url
	// from the array.
	$candidate_sites = array_diff($all_sites, array($site_url));

$display_urls = array();
foreach(array_rand($candidate_sites, 4) as $url)
	$display_urls[] = '<a href="http://'.$url.'/">'.ucfirst[$url].'</a>';

echo join(', ', $display_urls);
}
