MySQLi prepared statements: Short versions in one line - php

Question

In PHP, I use a lot of one liners like:
Fetch value:
$sql->query("SELECT ID FROM table WHERE condition = 1")->fetch_object()->ID;
Fetch row:
$sql->query("SELECT * FROM table WHERE condition = 1")->fetch_assoc();
Fetch rows:
$sql->query("SELECT * FROM table WHERE condition > 1")->fetch_all(MYSQLI_ASSOC);
Insert row:
$sql->query("INSERT INTO table(`row1`,`row2`) VALUES('".$data1."','".$data2."')");
Delete row:
$sql->query("DELETE FROM table WHERE condition = 1");
Are there also beautiful one liners for prepared statements?
This fails:
$sql->prepare("SELECT ID FROM table WHERE condition = ?")->bind_param("i", $a=1)->execute()->fetch_object()->ID;
This works:
$query = $sql->prepare("SELECT ID FROM table WHERE condition = ?");
$query->bind_param("i", $a=1);
$query->execute();
$query->get_result()->fetch_object()->ID;

Answer 1

Directly - there is no way. But you may use a simple overlay class which will allow you to do so.
class PrepareOverlay {
private $stmt;
private $lastResult = null;
public function __construct(PDOStatement $stmt) {
$this->stmt = $stmt;
}
public function __call($name, $arguments) {
$this->lastResult = call_user_func_array([$this->stmt, $name], $arguments);
return is_bool($this->lastResult) ? $this : $this->lastResult;
}
public function getLastResult() {
return $this->lastResult;
}
public static function prepare($sql, $query) {
return new self($sql->prepare($query));
}
}
And use it like this:
PrepareOverlay::prepare($sql, 'SELECT * FROM table WHERE cond = ?')->bindParam('i', $a=1)->execute()->fetchObject()->ID;
Although you will need some phpdoc to make code completion work.

if you consider using a framework like codeigniter you will be able to enjoy the Active record class, and you will be able to use something elegant like those lines :
$query = $this->db->get('mytable');
// Produces: SELECT * FROM mytable
or
$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);
or
$this->db->select('*');
$this->db->from('blogs');
$this->db->join('comments', 'comments.id = blogs.id');
$query = $this->db->get();
// Produces:
// SELECT * FROM blogs
// JOIN comments ON comments.id = blogs.id
you can also use chaining like this
$this->db->select('title')->from('mytable')->where('id', $id)->limit(10, 20);
$query = $this->db->get();
or
echo $this->db->count_all('my_table');
// Produces an integer, like 25
or
$this->db->delete('mytable', array('id' => $id));
// Produces:
// DELETE FROM mytable
// WHERE id = $id
and much more ... take a look at the documentation for a full documentation about active record
cheers !
