    Anyone have an idea on how I would go about limiting the number of headlines show up on a page that I use the PHP Include code on? My current code is below, thanks for the tips!

    <html>
<body bgcolor=#f4efce>

<basefont size=2 face=arial>

<b>Add Article</b>
<?
        include ("template.inc");
        include ("config.php");
	
	$subject = $_POST[subject];
	$summary = $_POST[summary];
	$passwd = $_POST[passwd];
	$date = $_POST[date];
	$author = $_POST[author];
	$body = $_POST[body];
	$article_id = $_POST[article_id];

	#foreach($GLOBALS as $a => $b){	print "<li>$a => $b";}

	$summary_template = "t_summary.php";
	$article_template = "t_article.php";
	$headline_template = "t_headline.php";
                $max_summary = 1;
                $max_headlines = 15;

	function summary_page ($subject, $date, $author, $summary, $article_id)
	{
		global $summary_template;
        	$t = new Template();
        	$t->set_file("SummaryPage", $summary_template);
		$article_url = "".$article_id.".php";
		$date = nl2br($date);
		$author = nl2br($author);
		$summary =  nl2br($summary);	 
		$t->set_var( array(
				"subject" => $subject,
				"date"    => $date,
				"author"    => $author,
				"summary" => $summary,
				"article_url" => $article_url
				));
		$t->parse("Summary", "SummaryPage");
		return $t->get_var("Summary");
	}

	function headline_page ($subject, $date, $author, $article_id)
	{
		global $headline_template;
        	$t = new Template();
        	$t->set_file("HeadlinePage", $headline_template);
		$article_url = "".$article_id.".php";
		$date = nl2br($date); 
		$author = nl2br($author);
		$t->set_var( array(
				"subject" => $subject,
				"date"    => $date,
				"author"    => $author,
				"article_url" => $article_url
				));
		$t->parse("Headline", "HeadlinePage");
		return $t->get_var("Headline");
	}

	function main_page ($subject, $date, $author, $summary, $article_id, $body)
	{
		global $article_template;

                $t = new Template();
                $t->set_file("ArticlePage", $article_template);
                $article_url = "".$article_id.".php";
                $date = nl2br($date);
                $author = nl2br($author);
                $summary =  nl2br($summary);
                $body =  nl2br($body);
                $t->set_var( array(
                                "subject" => $subject,

                                ));
                $t->parse("Article", "ArticlePage");
                return $t->get_var("Article"); 
	}

	function add_article($filename, $news)
	{

		if(file_exists($filename)){

		}
	}

    You tried changing $max_headlines = 15; from 15 to another value?

    $max_headlines was something that I edited into the config.php file. $max_summary was already in the file so I just kinda played around with it. Neither of the max_ codes work.

    In this case I don't think that the solution is in the code you shared. It might be where the functions are called or in the included files (config?)

    Alright, I'll take a look at it in the morning. It's an awkward script because it's PHPLib which is something I haven't really looked at yet, so the PHP in the other files looks almost 100% HTML with the exception of a couple things.

    Do you think that the solution is in the code below?

    

<?

        require('config.php'); 

	$filename = "article_summary.php";

	#- open article summaries
	if(file_exists($filename)){
		$fh = fopen($filename, "r");
		$old_news = fread($fh, filesize($filename));
		fclose($fh);
	}

 
	#- get first five article
	$articles = explode("<!--ARTICLE-->", $old_news);

	$i=0;
	foreach ( $articles as $article ){
		if(count($articles)>$i){
			if($max_latest >= $i++){
				print $article;
			}
		}
	}

?>
