PHP is breaking my code - php

Question

I'm trying to deploy a site but I get errors when the PHP/MySql code goes on the server. It worked fine in development but not in production.
My code gets down to here, with no problems:
<div class="content">
<section class="col1">
<h1>Read reviews or write us one</h1>
</section>
<section class="col2">
<button type="button" class="read">Read Reviews</button>
<?php include ('display.php'); ?>
Then when I check the source code, the HTML just stops there. I'm guessing there's something wrong with my PHP in the display.php file, which looks like this:
<?php
$con = mysql_connect('localhost','communi3_root',"password");
mysql_select_db('communi3_cfds','communi3#localhost',"password") or die(mysql_error());
$query = "select * from reviews";
$result = mysql_query($query)or die(mysql_error());
$row = mysql_fetch_array($result);
echo "<table class='displayReviews' border='1' style='width:100%;'>";
echo "<tr stlye='display:block;margin:0em auto;'><th>Name</th><th>Review</th><th>Date</th></tr>";
while ($row = mysql_fetch_array($result))
{
echo "<tr><td>";
echo $row['monicker'];
echo "</td><td>";
echo $row['review'];
echo "</td><td>";
echo $row['date'];
echo "</td></tr>";
}
echo "</table>";
mysql_close();
?>

Answer 1

after removing some error
<?php
$con = mysql_connect('localhost','communi3_root',"password");
mysql_select_db('communi3_cfds',$con) or die(mysql_error());
$query = "select * from reviews";
$result = mysql_query($query)or die(mysql_error());
$row = mysql_fetch_array($result);
echo "<table class='displayReviews' border='1' style='width:100%;'>";
echo "<tr stlye='display:block;margin:0em auto;'><th>Name</th><th>Review</th><th>Date</th></tr>";
while ($row = mysql_fetch_array($result))
{
echo "<tr><td>";
echo $row['monicker'];
echo "</td><td>";
echo $row['review'];
echo "</td><td>";
echo $row['date'];
echo "</td></tr>";
}
echo "</table>";
mysql_close();
?>
