Simple Redis Abstraction Layer

Installation with composer

Install library via composer

composer require tsk/simple-redis-dal

Initialization

Simple initialization

$db = new hooli("127.0.0.0", "password");

Check if eveything works

Simple check

$db->ping();

Handling simple values

Set a value

$key = "username";
$db->setvalue($key, "MaryPoppins");

Get the value

$username = $db->getvalue($key);

Delete a value

$key = "username";
$db->delete($key);

Cache a value

$key = "session_id";
$value = "12345";
$time = 20 // Time is in minutes

$db->cachevalue($key, $value, $time);

Expire a value

$key = "session_id";
$time = 1 // Time in minutes

$db->expire($key, $time);

Dealing with Hashes

Create a hash / Store data into a hash (record types structured as collections of field-value pairs)

$data = [
    "firstName" => "Mary",
    "lastName" => "Poppins",
    "email" => "marypoppins@email.com",
    "location" => "USA, New York"
];
$HashName = 'marypoppins@email.com';
$db->createhash($HashName, $data);

Check if a value exists in a hash

$HashName = 'marypoppins@email.com';
$db->checkhash($HashName, "firstName");

Update / replace a single value in a hash

$HashName = 'marypoppins@email.com';
$db->replacehash($HashName, "location", "Nigeria, Lagos");

Insert new value into hash

$HashName = 'marypoppins@email.com';
$db->inserthash($HashName, "age", 32);

Fetch all values in a single hash

$HashName = 'marypoppins@email.com';
$db->gethash($HashName);

or using return types
$db->json()->gethash($HashName);

Count the keys in a hash

$HashName = 'marypoppins@email.com';
$count = $db->countkeys($HashName);

Increase a value in a hash

$HashName = 'marypoppins@email.com';
$key = 'age'; // The value of this key must be an integer
$increaseBy = 4;
$db->increase($HashName, $key); // This method increases the value by one
$db->increaseby($HashName, $key, $increaseBy); // This method increases the value by the specified number

Dealing with lists

Insert value into a list

$List = "users";
$db->insertlist($List, "something@email.com");

search for a value inside a list

$List = "users";
if($db->search_list($List, "something@email.com")){
    echo 'value exists';
}

Count number of values /entries in a List

$List = "users";
$db->countlist($List);

Delete a List

$List = "users";
$db->deletelist($List);

Return all values in a List as JSON return type

$List = "users";
$db->json()->getlist($List);

Get a specific number of elements from a list

$List = "users";
$num = 10;
$users = $db->getlistnum($List, $num); // Returns an array

Dealing with HashLists

Save hashes to list (HashList) while mapping each value in list to key in hash

$data = [
    "firstName" => "Mary",
    "lastName" => "Poppins",
    "email" => "marypoppins@email.com",
    "location" => "USA, New York"
];
$list = "users";
$userID = "mary123";
$db->inserthashlist($userID, $data, $list);

Return all data in a HashList as json

$list = "users";
echo $db->gethashlist($list);

fetching specified number of keys in a list

list Name of the Redis list num is asigned the number of keys to be fetched

echo $db->getlistnum($list, $num)

Fetching specified number of hashes

list Name of the Redis list num reperesents the number of hashes to fetch from a list

echo $db->gethashlistnum($list, $num)
