Test

Design Pattern

run: php patterns/[folder-name]/test.php

for example,

chain of responsibility: run, php patterns/chainOfResponsibility/test.php

result：

request 5850c8354b298: token pass～
request 5850c8354b298: request frequent pass～
request 5850c8354b298: params pass～
request 5850c8354b298: sign pass～
request 5850c8354b298: auth pass～

Algorithm

run: php algorithm/test.php [algorithm name｜help]

for example,

bubble sort: run, php algorithm/test.php　bubble

result：

==========================bubble sort=========================
Array
(
    [0] => 11
    [1] => 67
    [2] => 3
    [3] => 121
    [4] => 71
    [5] => 6
    [6] => 100
    [7] => 45
    [8] => 2
)
=========up is the origin data==================below is the sort result=============
Array
(
    [0] => 2
    [1] => 3
    [2] => 6
    [3] => 11
    [4] => 45
    [5] => 67
    [6] => 71
    [7] => 100
    [8] => 121
)

Redis

run: php redis/test.php [name｜help]

for example,

pessimistic-lock: run, php redis/test.php p-lock

result：

exexute count increment 1～

count value: 1
