DTPDO

Extends php PDO functions and let you create CRUD query with arrays.

Let's explain functions by exampes.

In order to do our examples we need a table ...

CREATE TABLE IF NOT EXISTS `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
      `name` varchar(25) NOT NULL,
      `surname` varchar(25) NOT NULL,
      `age` int(11) NOT NULL,
      `city` varchar(25) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;

INSERT INTO `user` (`id`, `name`, `surname`, `age`, `city`) VALUES
(1, 'John', 'Smith', 32, 'Boston'),
(2, 'James', 'Brown', 39, 'New York'),
(3, 'Robert', 'Wilson', 52, 'Washington');

... and a instance of the class in a php file.

insertRecord

insertRecord($table, $param): Insert a record in a table by a given array of values

• param string $table: table name
• param array $param: associative array ("field1" => "value 1", ..., "fieldn" => "value n")

example #1

updateRecord

updateRecord($table, $param, $key): Update a record in a table by a ginen array

• param string $table: table name
• param array $param: associative array ("field1" => "value 1", ..., "fieldn" => "value n")
• param string/array $key

example #2

getValue

getValue($query, $fetchMode = PDO::FETCH_NUM): Get a value from a given query

• param string $query
• param string $fetchMode = PDO::FETCH_NUM
• return string : value of the first field of the first row

example #3

Code:

Function result:

Brown

getValues

getValues($query, $fetchMode = PDO::FETCH_NUM): Get an array of values from a given query

• param type $query
• param string $fetchMode = PDO::FETCH_NUM
• return array : vector of values of the query of the first row

example #4

Code:

Function result (array):

Array(
    id => 2
    name => James
    surname => Brown
    age => 39
    city => New York
);

getListValue

getListValue($query, $index = 1): Get an array of value, index is the first field of the query, value is the second field of the query

• param string $query
• param $index = 1, "1" array key is the first value of the quesry, "0" array key is incremental
• return array

example #5

Code: the index is the id value

Function result (array):

Array(
    2 => James
    3 => Robert
);

example #6

Code: the index is an incremental value

Function result (array):

Array(
    0 => James
    1 => Robert
);

getListValues

getListValues($query, $fetchMode = PDO::FETCH_NUM, $index = 0): Get an array of array, index is the first field of the query, array contains all the fields of the query

• param string $query
• param $fetchMode = PDO::FETCH_NUM
• param $index = 1, "1" array key is the first value of the quesry, "0" array key is incremental
• return array

example #7

Code: the array as an incremental index

Function result (array):

Array(
    0=> Array(
        0 => 1
        1 => John
        2 => Smith
        3 => 32
        4 => Boston
    );
    1=> Array(
        0 => 2
        1 => James
        2 => Brown
        3 => 39
        4 => New York
    );
    2=> Array(
        0 => 3
        1 => Robert
        2 => Wilson
        3 => 52
        4 => Washington
    );
);

example #8

Code: the first value is the key of the array

Function result (array):

Array(
    1=> Array(
        id => 1
        name => John
        surname => Smith
        age => 32
        city => Boston
    );
    2=> Array(
        id => 2
        name => James
        surname => Brown
        age => 39
        city => New York
    );
    3=> Array(
        id => 3
        name => Robert
        surname => Wilson
        age => 52
        city => Washington
    );
);
