SQL print/echo dumping php code into HTML

Question

I am very, very new to HTML/PHP so I'm probably going to misuse terminology, bear with me please.

I'm trying to print the results of my SQL query in HTML in a <p> element using <br> to separate them. I know it's not the best way but it's an easy one and will help me practice this.

Anyway my problem is instead of printing the "movieName" attribute I'm trying to print it dumps some of the PHP code into the <p> element body instead.

I don't know what information to provide to make it easier on you to spot the problem so please request any relevant details.

Here's the php code (I've "censored" my info because you can easily access my student account with it):

<?php
    if (array_key_exists('searchInput', $_GET)) {
        $search = $_GET['searchInput'];

        // Connecting, selecting database    
        $dbconn = pg_connect("host=**** port=15432 dbname=**** user=**** password=****") 
        or die('Could not connect: ' . pg_last_error());

        // Performing SQL query
        $query = "SELECT movieName 
                  FROM DatabaseProject.Movie M
                  WHERE M.movieName LIKE $search";
        $result = pg_query($query) or die('Query failed: ' . pg_last_error());

        // Printing results in HTML
        if ($result->num_rows > 0) {
            // output data of each row
            while($row = $result->fetch_assoc()) {
                $field = $row["movieName"];
                print("$field<br>");
            }
        } else {
            print("0 results");
        };

        // Free resultset
        pg_free_result($result);

        // Closing connection
        pg_close($dbconn);
    }
?>

This is what I get printed into the webpage:

num_rows > 0) { // output data of each row 
    while($row = $result->fetch_assoc()) { 
        $field = $row["movieName"]; 
        print("$field
        "); 
    } 
} else { 
    print("0 results"); 
}; 
// Free resultset pg_free_result($result); 
// Closing connection pg_close($dbconn); 
} 
?>
