Please how can I fix this.

<?php

$row['article_content'];

if (strlen($row['article_content']) > 500) {
  $shortText = substr($row['article_content'], 0, 100);
    $shortText .= '... <a href="site/article.php?id=' . $id . '">Read More</a>
 echo $shortText;

} ?>

Answer 1

<?php

if(isset($_GET['readmore']))
echo $row['article_content'];
else
echo get_short_text($row['article_content']); 


function get_short_text($article)
 {
   $shortText="";
   if (strlen($article) > 500) {
       $shortText = substr($article, 0, 100);
       $shortText .= '... <a href="site/article.php?id=' . $id . '&readmore=1'>Read More</a>
   }
   else { $shortText = $article; }

   return $shortText;
 }
