PHP function to print table in HTML

Answer to your question: No, there isn't.

However, I did find the idea interesting so I've written a function that does just that. However, your example uses MySQL() which is deprecated and insecure. So I'll be using a PDO class instead.

Please keep in mind that this function is only usefull for printing out a database table. It's NOT secure against injection and therefor should NEVER be used with user input inside the query!

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

include "pdo.class.php";

//Database data
define("DB_HOST", "localhost");
define("DB_USER", "");
define("DB_PASS", "");
define("DB_NAME", "");

function printTable($tbl_name, $db_query){
    //New PDO object
    $pdo = new Database();

    //Get column names
    $pdo->query("DESCRIBE ". $tbl_name);
    $col_names = $pdo->column();

    //Get number of columns
    $col_cnt = count($col_names);

    //Setup table - user css class db-table for design
    echo "<table class='db-table'>";
    echo "<tr colspan='". $col_cnt ."'>". $tbl_name ."</tr>";
    echo "<tr>";

    //Give each table column same name is db column name
    for($i=0;$i<$col_cnt;$i++){
        echo "<td>". $col_names[$i] ."</td>";
    }

    echo "</tr>";

    //Get db table data
    $pdo->query($db_query);

    $results = $pdo->resultset();
    $res_cnt = count($results);

    //Print out db table data
    for($i=0;$i<$res_cnt;$i++){
        echo "<tr>";
        for($y=0;$y<$col_cnt;$y++){
            echo "<td>". $results[$i][$col_names[$y]] ."</td>";
        }
        echo "</tr>";
    }
}

//Query
$sqlq = "SELECT * FROM tablename";

//Useage: printTable("tablename","query");
printTable("tablename",$sqlq);

?>

The PDO class itself:

Class Database{
    private $host = DB_HOST;
    private $user = DB_USER;
    private $pass = DB_PASS;
    private $dbname = DB_NAME;

    private $dbh;
    private $error;

    private $stmt;

    public function __construct(){
        // Set DSN
        $dsn = 'mysql:host=' . $this->host . ';dbname=' . $this->dbname;
        // Set options
        $options = array(
            PDO::ATTR_PERSISTENT    => true,
            PDO::ATTR_ERRMODE       => PDO::ERRMODE_EXCEPTION
        );
        // Create a new PDO instanace
        try{
            $this->dbh = new PDO($dsn, $this->user, $this->pass, $options);
        }
        // Catch any errors
        catch(PDOException $e){
            $this->error = $e->getMessage();
        }
    }

    public function query($query){
        $this->stmt = $this->dbh->prepare($query);
    }

    public function bind($param, $value, $type = null){
        if (is_null($type)) {
            switch (true) {
                case is_int($value):
                    $type = PDO::PARAM_INT;
                    break;
                case is_bool($value):
                    $type = PDO::PARAM_BOOL;
                    break;
                case is_null($value):
                    $type = PDO::PARAM_NULL;
                    break;
                default:
                    $type = PDO::PARAM_STR;
            }
        }
        $this->stmt->bindValue($param, $value, $type);
    }

    public function execute(){
        return $this->stmt->execute();
    }

    public function column(){
        $this->execute();
        return $this->stmt->fetchAll(PDO::FETCH_COLUMN);
    }

    public function resultset(){
        $this->execute();
        return $this->stmt->fetchAll(PDO::FETCH_ASSOC);
    }

    public function single(){
        $this->execute();
        return $this->stmt->fetch(PDO::FETCH_ASSOC);
    }

    public function rowCount(){
        return $this->stmt->rowCount();
    }

    public function lastInsertId(){
        return $this->dbh->lastInsertId();
    }

    public function beginTransaction(){
        return $this->dbh->beginTransaction();
    }

    public function endTransaction(){
        return $this->dbh->commit();
    }

    public function cancelTransaction(){
        return $this->dbh->rollBack();
    }

    public function debugDumpParams(){
        return $this->stmt->debugDumpParams();
    }
