Lists
, (*1)
You can install library through Composer:, (*2)
{
"require": {
"sokil/php-list": "dev-master"
}
}
Priority map allows you to specify priority of items and iterate through this list in order to priority., (*3)
Add elements to list with priority:, (*4)
<?php
$list = new \Sokil\DataType\PriorityMap();
$list->set('key1', 'value1', 10);
$list->set('key2', 'value2', 100);
Get elements according to priority:, (*5)
<?php
foreach($list as $key => $value) {
echo $key . ' - ' . $value;
}
// this will print
// key2 - value2
// key1 - value1
Get element by key:, (*6)
<?php
$list = new \Sokil\DataType\PriorityMap();
$list->set('key1', 'value1', 10);
$list->get('key1');
Weight list allows you to specify values and relative weights, and randomly get value according to it's weight., (*7)
Imagine that we have three database servers with ip addresses: 10.0.0.1, 10.0.0.2 and 10.0.0.3. We want to balance connections between nodes with weights 60%, 30% and 10%. So most connections goes to server 10.0.0.1, than to 10.0.0.2 and than to 10.0.0.3., (*8)
<?php
$list = new \Sokil\DataType\WeightList([
'10.0.0.1' => 60,
'10.0.0.2' => 30,
'10.0.0.3' => 10,
]);
$ipAddress = $list->getRandomValue();
Now we have address on every request relatively to it's weight., (*9)
