An aiml parser for PHP

0. notice

the chatbot is written according to AIML 2.5 and Program-P，it uses utf-8 and i made some customization , there are some differences between standard aiml tags and the tags used in this program.

1. description

it is working well on PHP5.4 and Apache server .

2. database configuration

you should use MySQL database and import the chatbot.sql file to your database . then, you should configure your database information in chatbot/Config.php file .

4. aiml sourses

you can edit aiml/chatbot.aiml fiel directly or create an aiml file in aiml directory and include it in aiml/chatbot.aiml file。

5. about aiml files

  • aiml files should be paleced in aiml directory.
  • chatbot.aimlis the entrance ，the aiml tag in it can contain various category tag , a defaulttag and various includetag。
  • other aiml files writen by you should contain a topic tag in root aiml tag , and the topic can contain various category tag and a default tag (it should not have include tag)。

6. test

you can visit index.php to test it.

7. using the chatbot

if you want to use the chatbot in your application, you can request api.php?requestType=talk&userInput=hello。

8. about the regular expressions

Modified matching rules :

* ---> (\S+)
# ---> \S+
_ ---> .*
= ---> \S*

9. about aiml tags

it is different from the standard aiml，i made some customizaton to aiml tags , you can see the tag rules in AIML.MD file。

10. about the response of api.php

{
    "status": "success",
    "type": "talk",
    "message": "haha ...",
    "data": {
        "arr1": {
            "name11": "value11",
            "name12": "value12"
        },
        "arr2": {
            "name21": "value21",
            "name22": "value22"
        }
    }
}

you will get above response when you visit api.php?requestType=talk&userInput=haha and you have a category like this .

<category>
    <pattern>haha</pattern>
    <template>
        <data name="arr1">
            <attr name="name11">value11</attr>
            <attr name="name12">value12</attr>
        </data>
        <data name="arr2">
            <attr name="name21">value21</attr>
            <attr name="name22">value22</attr>
        </data>
        haha ...
    </template>
</category>

11. about userId

when you send a userId param as a get param , this will be used as a unique identity of user , or the program will use user's ip instead of it .

$userId = isset($_REQUEST['userId']) ? $_REQUEST['userId'] : $_SERVER['REMOTE_ADDR'];

12. about multi chatbot

if you set the multiChatbot variable false in 'chatbot/Config.php' , all users share a default chatbot . and if you set it true , every user will have a unique chatbot and we will set the chatbot informations in template tag , like botName , botAge , botSex and others , this will be verry usefull when you are building a voice assistant app and hoping the users can reaname your app . the multi chatbot also uses the userId(ip or the value you send it to chatbot) as a unique identity .

$user = $this->getUser($this->_unique);
if ($this->_config->multiChatbot){
    $bot = $this->getBot($this->_unique);
} else {
    $bot = $this->getBot("default");
}

13. about userInfo and botInfo

userInfo is user's properties like name , sex and age . then , botInfo is similar too . botInfo is the bot's information serving for the user . if you using multi chatbot mode , every user can change their bot's informations , they can rename it , and give it a age . for usage you can view the AIML.MD file and study about the tags like set, get, del, user, bot.

<category>
    <pattern>my name is *</pattern>
    <template>
        ok , your name is
        <star/>
        <set type="user" name="name">
            <star/>
        </set>
    </template>
</category>

<category>
    <pattern>what is my name</pattern>
    <template>
        oh , your name is
        <get type="user" name="name"/>
        , i remembered it last time ...
    </template>
</category>

14. about database

log table is for logging .

property table is for storing the userInfo and botInfo , it is the memory of the chatbot . set ,get, del, user, bot tags are operating this table .

data table is for storing the words spoken by user and bot . input , that, topic tags will operate Parser::$_data array and the array will be saved to data table when the program is finishing . then , it will be loaded at the next time users requests the chatbot program . the unique key in data table is userId(ip or the value you send it to chatbot) too.

Enjoy it
