This package is abandoned. Consider upgrading to bentools/where, a very easy way to generate conditions and full queries on the fly.

MySkewHell - Tuple

An intuitive way to work with MySql prepared statements.

Use the PHP array syntax to dynamically add conditions on a SQL query.

Each value will be transfomed to a placeholder ; you can then bind each placeholder to its value.

Building a query : working with placeholders and values

positional placeholders (default)

$sql        =   "SELECT * FROM users WHERE 1" . PHP_EOL;
$tuples     =   new TupleANDWrapper();
$tuples[]   =   ['nickname' => 'johndoe'];
$tuples[]   =   ['firstname', '=', 'John'];
$tuples[]   =   ['lastname', 'LIKE', 'Doe'];
$tuples[]   =   new TupleORWrapper([
                                    ['active' => true], 
                                    ['date_registered', 'BETWEEN', ['2015-01-01', '2015-01-30']]
                                    ]);
$tuples[]   =   ['id_group', 'NOT IN', [5, 8, 15]];
$tuples[]   =   ['nb_logins', '>=', 2];
$tuples[]   =   "lastloggedin <= CURRENT_DATE - INTERVAL 1 MONTH";

$sql        .=  'AND ' . $tuples;

var_dump($sql);

Output :

SELECT *
    FROM users
WHERE 1
    AND (
          `nickname` = ?
          AND `firstname` = ?
          AND `lastname` LIKE ?
          AND (
                (`active` = ?  
                  OR `date_registered` BETWEEN ? AND ?)
              )
          AND `id_group` NOT IN (?, ?, ?)
          AND `nb_logins` >= ?
          AND lastloggedin <= CURRENT_DATE - INTERVAL 1 MONTH
        )
var_dump($tuples->getPlaceHolders());

Output :

  9 => string '?' (length=1)

var_dump($tuples->getValues());

Output :

$tuples[]   =   ['id_group', 'NOT IN', [5, 8, 15]];
$tuples[]   =   ['nb_logins', '>=', 2];
$tuples[]   =   "lastloggedin <= CURRENT_DATE - INTERVAL 1 MONTH";

// Same code here : just specify we want to use named placeholders
$tuples     ->  useNamedPlaceholders(true);

$sql        .=  'AND ' . $tuples;

var_dump($sql);

Examples with PDO

Using positional placeholders

$pdo        =   new PDO("mysql:host=localhost;dbname=mydb", "username", "password");
$stmt       =   $pdo->prepare($sql);

foreach ($tuples AS $key => $value)
    $stmt->bindValue(++$key, $value);

$stmt->execute();
var_dump($stmt->fetchAll(PDO::FETCH_ASSOC));

Using named placeholders

$pdo        =   new PDO("mysql:host=localhost;dbname=mydb", "username", "password");
$stmt       =   $pdo->prepare($sql);

foreach ($tuples AS $key => $value)
    $stmt->bindValue(sprintf(':%s', $key), $value);

$stmt->execute();
var_dump($stmt->fetchAll(PDO::FETCH_ASSOC));

Examples with PDOExtended

Using positional placeholders

$pdo        =   new PDOExtended("mysql:host=localhost;dbname=mydb", "username", "password");
$stmt       =   $pdo->prepare($sql);
var_dump($stmt->sqlArray($tuples->getValues()));

Using named placeholders

$pdo        =   new PDOExtended("mysql:host=localhost;dbname=mydb", "username", "password");
$stmt       =   $pdo->prepare($sql);
var_dump($stmt->sqlArray($tuples->getValues()));

Operators

Comparison operators

['my_column', '=', 'my_string']; // will output "`my_column` = ?"
['my_column', 'LIKE', 'my_string%']; // will output "`my_column` LIKE ?"
['my_column', '>=', 2]; // will output "`my_column` >= ?"
['my_column', '>', 2]; // will output "`my_column` > ?"
['my_column', '<=', 2]; // will output "`my_column` <= ?"
['my_column', '<', 2]; // will output "`my_column` < ?"
['my_column', '<>', 2]; // will output "`my_column` <> ?"
['my_column', '!=', 'my_string]; // will output "`my_column` != ?"

Simple range operator

['my_column', 'BETWEEN', ['2015-01-01', '2015-01-30']]; // will output "`my_column` BETWEEN ? AND ?"

Multiple range operators

['my_column', 'IN', [5, 3]]; // will output "`my_column` IN (?, ?)"
['my_column', 'NOT IN', [8, 6, 9, 12]]; // will output "`my_column` NOT IN (?, ?, ?, ?)"

Shortcut

['my_column' => 'my_string']; // will output "`my_column` = ?"

Wrappers

"AND" wrapper

$tuples     =   new TupleANDWrapper();
$tuples[]   =   ['my_column', 'IN', [5, 3]]; // will output "`my_column` IN (?, ?)"
$tuples[]   =   ['my_column', 'NOT IN', [8, 6, 9, 12]]; // will output "`my_column` NOT IN (?, ?, ?, ?)"
var_dump((string) $tuples)); // will output "(`my_column` IN (?, ?) AND `my_column` NOT IN (?, ?, ?, ?))"

"OR" wrapper

$tuples     =   new TupleORWrapper();
$tuples[]   =   ['my_column', 'IN', [5, 3]]; // will output "`my_column` IN (?, ?)"
$tuples[]   =   ['my_column', 'NOT IN', [8, 6, 9, 12]]; // will output "`my_column` NOT IN (?, ?, ?, ?)"
var_dump((string) $tuples)); // will output "(`my_column` IN (?, ?) OR `my_column` NOT IN (?, ?, ?, ?))"

"String" wrapper

$tuples     =   new TupleORWrapper();
$tuples[]   =   ['my_column', 'BETWEEN', ['2015-01-01', '2015-01-30']]
$tuples[]   =   "`another_column` >= CURRENT_DATE - INTERVAL 3 DAY"
var_dump((string) $tuples)); // will output "(`my_column` BETWEEN ? AND ? OR `another_column` >= CURRENT_DATE - INTERVAL 3 DAY"
