PHP SQL search not returning any results - php

Question

I'm trying to make a search bar to search my db but it always returns 0 results,
Here is the Connect and search code,
<?php
$serverName = "server";
$connectionInfo = array( "Database"=>"server");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
$output ='';
if(isset($_POST['PartSelect'])){
$searchq = $_POST['PartSelect'];
$query = sqlsrv_query($conn, "SELECT * FROM Parts WHERE PartNumber LIKE '%$searchq%'") or die ("Could not search");
$count = sqlsrv_num_rows($query);
if($count == 0){
$output = 'There are no results';
----- This Section is new error Code -----
$rows = sqlsrv_has_rows( $query );
if ($rows === true)
echo "\nthere are rows\n";
else
echo "\nno rows\n";
---- End Section ------
This prints saying it has rows so it it picking up the data,
}
else {
while ($row = sqlsrv_fetch_array($query)){
$Partno = $row['PartNumber'];
$output .= '<div>'.$PartNo. '</div>';
}
}
?>
Here is the search bar and submit button (I am using materialize as a framework), and the output at the end.
<form action="Tests.php" method="post">
<div class="form-group">
<br/><input name="PartSelect" type="text" class="form-control" id="PartSelect" aria-describedby="nameHelp" placeholder="Enter Part">
<br/><button name="SelectPartbtn" id="Submitbtn" type="Submit" class="waves-effect waves-light btn">Find</button>
</div>
<?php print ("$output"); ?>
</form>

try with this code check connection is made or not
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = sqlsrv_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . sqlsrv_errors());
}
