I have a database class dbconnect.php, and processform.php. Inside dbconnect.php there is a method for connecting to the database.
If there's an error, how do I throw an exception? Where do I put the try catch block, in the processform.php? People say I shouldn't echo an error directly from inside the class. Here's an example:
<?php
// dbconnect.php
class DbConnect
{
public function open_connection()
{
/* Should I do it like this? */
$this->conn = PDO($dsn, $this->username, $this->password);
if (!$this->conn) {
throw new Exception('Error connecting to the database.');
}
/* Or like this */
try {
$this->conn = PDO($dsn, $this->username, $this->password);
} catch (PDOException $e) {
echo 'Error: ', $e->getMessage(), '<br>';
}
}
?>
// processform.php
<?php
require_once 'dbconnect.php';
$pdo = new DbConnect($host, $username, $password);
try {
$pdo->open_connection();
} catch (PDOException $e) {
echo 'Error connecting to the database.');
}
?>
I really want to learn the correct way of implementing the try catch in my code.
