Help with PHP news system

PHP
1

I am using MaxNews PHP script for a project.
Basically the script allows me to enter content via an admin panel and I just PHP include the content in my home page.

The problem I am having is that the I ONLY WANT 1 (ONE) news article showing at once only. The script by default has it showing them ALL!
How can I fix this?

The files:

maxNews.class.php

<?php
/**
 * Max News
 *
 * This is the Max News business logic class.
 * For more details please read the readme.txt
 */
?>
<?php
class maxNews{
   var $newsDir = 'news';
   var $newsList;
   var $newsCount = 1;

function getNewsList(){
	
   $this->newsList = array();

	// Open the actual directory
	if ($handle = @opendir($this->newsDir)) {
		// Read all file from the actual directory
		while ($file = readdir($handle))  {
		    if (!is_dir($file)) {
		       $this->newsList[] = $file;
      	}
		}
	}	
	
	rsort($this->newsList);
	
	return $this->newsList;
}

function getNewsCount(){
   if ($this->newsCount == 1) $this->getNewsList();
   $this->newsCount = sizeof($this->newsList);
   return $this->newsCount;
}

function displayNews(){
      $list = $this->getNewsList();

      echo "<table class='newsList'>";
      foreach ($list as $value) {
      	$newsData = file($this->newsDir.DIRECTORY_SEPARATOR.$value);
      	$newsTitle  = $newsData[0];
         $submitDate = $newsData[1];	
         unset ($newsData['0']);
         unset ($newsData['1']);
      	
         $newsContent = "";
         foreach ($newsData as $value) {
    	       $newsContent .= $value;
         }
      	
      	echo "<tr><th align='left'>$newsTitle</th>
      	          <th class='right'>$submitDate</th></tr>";
      	echo "<tr><td colspan='2'>".$newsContent."<br/></td></tr>";
      }
      echo "</table>";
      if (sizeof($list) == 0){
         echo "<center><p>No news at the moment!</p><p>&nbsp;</p></center>";
      }
}

Before the loop add the following which will force only one article to be shown:

$list = $list[0];

See the below for a much cleaner output of the function which will avoid errors in the loop if the $list array is empty:

function displayNews() {
    $list = $this->getNewsList();

    if (sizeof($list) >= 1) {
        $list = $list[0];
        
        echo "<table class='newsList'>";

        foreach ($list as $value) {
            $newsData   = file($this->newsDir . DIRECTORY_SEPARATOR . $value);
            $newsTitle  = $newsData[0];
            $submitDate = $newsData[1];    
            unset($newsData[0]);
            unset($newsData[1]);

            $newsContent = '';

            foreach ($newsData as $value) {
                $newsContent .= $value;
            }

            echo "<tr>";
            echo "    <th align='left'>" . $newsTitle . "</th>";
            echo "    <th class='right'>" . $submitDate . "</th>";
            echo "</tr>";
            echo "<tr>";
            echo "    <td colspan='2'>" . $newsContent . "<br/></td>";
            echo "</tr>";
        }

        echo "</table>";
    } else {
        echo "<center><p>No news at the moment!</p><p>&nbsp;</p></center>";
    }
}
