build and replace

pneudralics

	
if ( $p = red_sql_query("polls","*","ORDER BY rand() LIMIT 1",TRUE) )
	{
		$count = 0;

	$POLLS = "";
	$split = split(",","$p[option]");
	foreach ($split as $poll)
	{
		$count++;
		$POLLS .= '<div><input type="radio" name="an" class="pollinput" value="o'.$count.'" onclick="submit();" style="vertical-align:middle;" />' .$poll.'</div>'."\n";
	}

	$red_build['POLL_USER_IMAGE'] = uimage($p['user'],"60",4,"");
	$red_build['POLL_ID'] = $p['id'];
	$red_build['POLL_VALUE'] = $p['poll'];
	$red_build['POLL_TEXT'] = $p['poll'];
	$red_build['POLL_OPTIONS'] = $POLLS;	
	$red_replace['red_polls'] = 1;
	$red_build['POLL_LINK'] = red_links("poll","result",$p['id']);
}

Can someone help tell me what build and replace means and does? This is one of the scripts to build a poll, but I dont understand build and replace.

$red_build and $red_replace are arrays.

pneudralics

what do they do?

Store data.

They are a collection of variables http://www.phpit.net/article/back-to-basics-arrays/

So..
$red_build['POLL_ID'] = $p['id'];

$red_build is a variable that's part of the array $POLLS?
= $p['id']; Anything listed in that is where the variable gets the value from?
Anything listed in [''] is the value of $red_build?

When you write $POLLS then it displays the entire array?
