Using the PDO class
===================
##Insert a new record
Firstly you need to instantiate a new database.
```php
$database = new Database();
```
Next we need to write our insert query. Notice how I’m using placeholders instead of the actual data parameters.
```php
$database->query('INSERT INTO mytable (FName, LName, Age, Gender) VALUES (:fname, :lname, :age, :gender)');
```
Next we need to bind the data to the placeholders.
```php
$database->bind(':fname', 'John');
$database->bind(':lname', 'Smith');
$database->bind(':age', '24');
$database->bind(':gender', 'male');
```
And finally we run execute the statement.
```php
$database->execute();
```
Before running the file, echo out the lastInsertId function so you will know that the query successfully ran when viewed in the browser.
```php
echo $database->lastInsertId();
```
##Insert multiple records using a Transaction
The next test we will try is to insert multiple records using a Transaction so that we don’t have to repeat the query.
The first thing we need to do is to begin the Transaction.
```php
$database->beginTransaction();
```
Next we set the query.
```php
$database->query('INSERT INTO mytable (FName, LName, Age, Gender) VALUES (:fname, :lname, :age, :gender)');
```
Next we bind the data to the placeholders.
```php
$database->bind(':fname', 'Jenny');
$database->bind(':lname', 'Smith');
$database->bind(':age', '23');
$database->bind(':gender', 'female');
```
And then we execute the statement.
```php
$database->execute();
```
Next we bind the second set of data.
```php
$database->bind(':fname', 'Jilly');
$database->bind(':lname', 'Smith');
$database->bind(':age', '25');
$database->bind(':gender', 'female');
```
And run the execute method again.
```php
$database->execute();
```
Next we echo out the lastInsertId again.
```php
echo $database->lastInsertId();
```
And finally we end the transaction
```php
$database->endTransaction();
```
##Select a single row
The next thing we will do is to select a single record.
So first we set the query.
```php
$database->query('SELECT FName, LName, Age, Gender FROM mytable WHERE FName = :fname');
```
Next we bind the data to the placeholder.
```php
$database->bind(':fname', 'Jenny');
```
Next we run the single method and save it into the variable $row.
```php
$row = $database->single();
```
Finally, we print the returned record to the screen.
```php
echo "
";
print_r($row);
echo "
";
```
##Select multiple rows
The final thing we will do is to run a query and return multiple rows.
So once again, set the query.
```php
$database->query('SELECT FName, LName, Age, Gender FROM mytable WHERE LName = :lname');
```
Bind the data.
```php
$database->bind(':lname', 'Smith');
```
Run the resultSet method and save it into the $rows variable.
```php
$rows = $database->resultSet();
```
Print the return records to the screen.
```php
echo "
";
print_r($rows);
echo "
";
```
And finally display the number of records returned.
```php
echo $database->rowCount();
```
