[SOLVED] Has to be explode

steelmanronald06 · November 5, 2009

Okay, here's the deal. I think my eyes are crossing from working on the computer for the past 6 hours (google maps api, twitter, etc). Very frustrating. Anyways, I'm having a problem that I think revolves with explode().

Go to: http://www.oldhatcreative.com/newohtestground/twitter/

Okay now hover over a link for someone. Lets say oldhatcreative. The link reads:

http://www.twitter.com/oldhatcreative</uri>    </author>

Obviously I don't want it to read like that, but I can't see to figure out how to strip out that </uri> </author>. By all accounts it should be there.

Second problem. Hover over any of the links in the actual tweets. They display as:

http://www.oldhatcreative.com/newohtestground/twitter/"http://linkdomain.tld"

I want links to parse as normal html links...and they should. If you go to http://search.twitter.com/search.atom?q=from%3aoldhatcreative and View Source, you'll see that twitter nicely puts that stuff into <a href="">...</a> tags for me!

Now for my code.

<?php
/*
Relative Time Function

define("SECOND", 1);
define("MINUTE", 60 * SECOND);
define("HOUR", 60 * MINUTE);
define("DAY", 24 * HOUR);
define("MONTH", 30 * DAY);
function relativeTime($time)
{
$delta = strtotime('+2 hours') - $time;
if ($delta < 2 * MINUTE) {
	return "1 min ago";
}
if ($delta < 45 * MINUTE) {
	return floor($delta / MINUTE) . " min ago";
}
if ($delta < 90 * MINUTE) {
	return "1 hour ago";
}
if ($delta < 24 * HOUR) {
	return floor($delta / HOUR) . " hours ago";
}
if ($delta < 48 * HOUR) {
	return "yesterday";
}
if ($delta < 30 * DAY) {
	return floor($delta / DAY) . " days ago";
}
if ($delta < 12 * MONTH) {
	$months = floor($delta / DAY / 30);
	return $months <= 1 ? "1 month ago" : $months . " months ago";
} else {
	$years = floor($delta / DAY / 365);
	return $years <= 1 ? "1 year ago" : $years . " years ago";
}
}
?>

I'm not really familiar with the structure, and it's hard to decipher someone else's code but the easiest solution would be just to use strip_tags.

$super_clean_name = strip_tags($super_clean_name_1[1]);

Awesome, AlexWD. Like I said, my brain is shutting down. Completely spaced on the php strip_tag() function.

Anyone have any ideas on the second problem? I can't figure out why <a href""> tags would be thrown at the end of my domain name.

Whoops, forgot to address your second problem

You're gonna want to use echo html_entity_decode(). Ex:

echo html_entity_decode($clean_content[0]);

Because if you look at their source they use html entities for the quotes inside the a tag.

Perfect, Alex. Thanks a million. I obviously need to take a step away from the computer. Just spent 5 hours coding Google Maps API into our site, linking it to a geocode library so I can get long/lat, editing all the stupid little buttons and everything.

Anyways, thanks again.
