How to remove/hide text at the very top of the page - php

Question

Problem
I would like to know how I would make the text at the top of the screen not show when connecting or searching the database. Below is a screenshot of what I am talking about.
Is it possible for it to not appear at all? Below is the code that connects to the database, as well as the code for the form below.
Code
The code to connect to the database:
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=***** port=*****
dbname=***** user=***** password=*****")
or die('Could not connect: ' . pg_last_error());
//collect
if(isset($_POST['search'])) {
$searchq = $_POST['search'];
// $searchq = preg_replace("#[^0-9a-z]#i"."".$searchq);
// Performing SQL query
$query = "SELECT vegan FROM enumbers WHERE code LIKE '%$searchq%'";
$ret = pg_query($dbconn, $query);
if(!$ret){
echo pg_last_error($dbconn);
exit;
}
$output = '';
while($row = pg_fetch_assoc($ret)){
$code = $row['code'];
print_r($row);
$name = $row['name'];
$type = $row['type'];
$vegan = $row['vegan'];
$output .= '<div> '.vegan.' ';
}
}
echo "Operation done successfully\n";
pg_close($dbconn);
?>
The code for the form:
<div id="tablebox">
<!-- Search bar -->
<p>Is It Vegan?</p>
<form name="form1" method="post" action="searchEnumbers.php">
<input name="search" type="text" size="30" maxlength="5" />
<input name="submit" type="submit" value="Search" />
</form>
<?php
print("$output");
?>
</div>
</div>

Answer 1

Just remove these two lines from your code
print_r($row);
.....
echo "Operation done successfully\n";

Answer 2

Try this one, Changes are noted via php comment (//)
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=***** port=*****
dbname=***** user=***** password=*****")
or die('Could not connect: ' . pg_last_error());
//collect
if(isset($_POST['search'])) {
$searchq = $_POST['search'];
// $searchq = preg_replace("#[^0-9a-z]#i"."".$searchq);
// Performing SQL query
$query = "SELECT vegan FROM enumbers WHERE code LIKE '%$searchq%'";
$ret = pg_query($dbconn, $query);
if(!$ret){
echo pg_last_error($dbconn);
exit;
}
$output = '';
while($row = pg_fetch_assoc($ret)){
$code = $row['code'];
//Commented 1
//print_r($row);
$name = $row['name'];
$type = $row['type'];
$vegan = $row['vegan'];
$output .= '<div> '.vegan.' ';
}
}
//Commented 2
//echo "Operation done successfully\n";
pg_close($dbconn);
?>
