How to delete records?

1) Write the delete statement:

$sql = "DELETE FROM `users` WHERE `id`=:id";

1	$sql = "DELETE FROM `users` WHERE `id`=:id";

2) Prepare the query:

$query = $dbh -> prepare($sql);

1	$query = $dbh -> prepare($sql);

3) Bind the parameters:

$query -> bindParam(':id', $id, PDO::PARAM_INT);

1	$query -> bindParam(':id', $id, PDO::PARAM_INT);

4) Define the bound values:

$id = 1;

$id = 1;

5) Execute the query:

$query -> execute();

1	$query -> execute();

6) Check that the query has been performed and that the records have been successfully deleted from the database.

if($query -> rowCount() > 0)
{
$count = $query -> rowCount();
echo $count . " rows were affected.";
}
else
{
echo "No affected rows.";
}

if($query -> rowCount() > 0)

{

$count = $query -> rowCount();

echo $count . " rows were affected.";

}

else

{

echo "No affected rows.";

}

All code together now:

$sql = "DELETE FROM `users` WHERE `id`=:id";
$query = $dbh -> prepare($sql);
$query -> bindParam(':id', $id, PDO::PARAM_INT);
$id = 1;
$query -> execute();
if($query -> rowCount() > 0)
{
$count = $query -> rowCount();
echo $count . " rows were affected.";
}
else
{
echo "No affected rows.";
}
