Forked From philwc/JsonDB with many modifications

Handle JSON-Files like a very, very simple DB. Useful for little ajax applications.

Example:

test.json

[
{"ID": 0, "Name": "Josef Brunzer", "Age": 43},
{"ID": 1, "Name": "Harald Beidlpraka", "Age": 34},
{"ID": 2, "Name": "Heinz Goschnfuada", "Age": 67},
{"ID": 3, "Name": "Gerald Ofnsacka", "Age": 43}
]

test.php

require '../vendor/autoload.php';
$db = new \nyankod\JsonDB('./data/');
$db->setTable('test');
$result = $db->select('Age', 43);
var_dump($result);

result:

array(2) {
  [0]=> array(3) { ["ID"]=> int(0) ["Name"]=> string(13) "Josef Brunzer" ["Age"]=> int(43) }
  [1]=> array(3) { ["ID"]=> int(3) ["Name"]=> string(15) "Gerald Ofnsacka" ["Age"]=> int(43) }
}

The default extension is .json. If you want to use a different file extension as ".dat" or whatever, set it in second parameter when create object, $db = new \nyankod\JsonDB('./data/', '.dat');

Method Overview

JsonDB -> setTable ( "tablename" ) - Set tablename or create table file if not exist. This method have to always be called before doing data transaction.

JsonDB -> select ( "key", "value" ) - Selects multiple lines which contains the key/value and returns it as array

JsonDB -> selectAll () - Returns the entire file as array

JsonDB -> update ( "key", "value", ARRAY ) - Replaces the line which corresponds to the key/value with the array-data

JsonDB -> updateAll ( ARRAY ) - Replaces the entire file with the array-data

JsonDB -> insert ( ARRAY ) - Appends a row, returns true on success

JsonDB -> delete ( "key", "value" ) - Deletes all lines which corresponds to the key/value, returns number of deleted lines

JsonDB -> deleteAll () - Deletes the whole data, returns "true" on success
