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 "JsonDB.class.php";

$db = new JsonDB("./data/"); //parameter => directory to your json files

$result = $db->select("test","Age",43); //parameter => json file (tablename), key, value

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) }
}

If you use a different file extension as ".json", set them via "JsonDB -> setExtension ('.example')"

Method Overview:

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

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

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

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

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

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

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

If you use only one json file to store data, you can also use the "JsonTable" Class:

$db = new JsonTable("./data/test.json"); //parameter => your json file

$result = $db -> selectAll();

$db -> update ( "ID", 1, array("ID" => 1, "Name" => "Fani Zwidawurzn", "Age" => 66));

$db -> delete( "ID", 2 );

In this case, you don't have always to specify the "tablename".
