mapepire-php

mapepire-php is a PHP client for the Mapepire database access layer for Db2 on IBM i.

⚠️ (WIP!) This Project is a work in progress, more features are coming

Summary

mapepire-php currently consists of two classes:

• DaemonServer
  • a structure for initializing an SQLJob
• SQLJob
  • the basic client which can connect, send a JSON request to the mapepire-server, and receive a response

Installation

From the repository

• Clone the repository and use PHP Composer to do composer install to download the component packages.
• In your code require_once('vendor/autoload.php'); will pull in the component packages along with mapepire-php classes.

From Composer

• To be implemented

Usage

Usage synopsis

The simplest use is to instance an SQLJob and use its instance method singleSendAndReceive() to send JSON and receive a JSON response.

The response comes in the form of a phrity/websocket \WebSocket\Message\Text object.

Use the \WebSocket\Message\Text instance method getContent() to get the JSON message content.

You may further more use any other \WebSocket\Message\Text instance method on the response to examine the response and help debug your code.

Instancing SQLJob

There are 3 ways to instance SQLJob:

1. The SQLJob constructor with its numerous arguments, all of which default to "reasonable" values.
   • Of course, userid and password cannot default.
2. SQLJob::SQLJobFromDotEnv() which uses vlucas/phpdotenv to load a .env file in a specified directory.
   • See the .env.sample file is the root directory of the project.
3. SQLJob::SQLJobFromDaemonServer() which takes an instance of DaemonServer.

Instancing DaemonServer

There are 2 ways to instance DaemonServer.

1. The DaemonServer constructor with its numerous arguments, all of which default to "reasonable" values.
2. DaemonServer::DaemonServerFromDotEnv() which uses vlucas/phpdotenv to load a .env file in a specified directory.
   • See the .env.sample file is the root directory of the project.

Example session

Assuming a reasonble .env file in the current directory, in interpretive PHP (php -a):

php > require_once('vendor/autoload.php');
php > $ds = Mapepire\DaemonServer::DaemonServerFromDotEnv('.');
php > $sj = Mapepire\SQLJob::SQLJobFromDaemonServer($ds);
php > $result = $sj->singleSendAndReceive('{"id": "foo", "type": "connect"}');
php > print($result->getContent());
{"id":"foo","job":"242155/QUSER/QSQSRVR","success":true}
php > $result = $sj->singleSendAndReceive('{"id": "bar", "type": "sql", "sql": "select * from sample.employee"}');
php > print($result->getContent());
{"id":"bar","has_results":true,"update_count":-1,"metadata":{"column_count":14,"job":"242155/QUSER/QSQSRVR","columns":[{"name":"EMPNO","type":"CHAR","display_size":6,"label":"EMPNO"},{"name":"FIRST_NAME","type":"VARCHAR","display_size":12,"label":"FIRST_NAME"},{"name":"MIDINIT","type":"CHAR","display_size":1,"label":"MIDINIT"},{"name":"LASTNAME","type":"VARCHAR","display_size":15,"label":"LASTNAME"},{"name":"WORKDEPT","type":"CHAR","display_size":3,"label":"WORKDEPT"},{"name":"PHONENO","type":"CHAR","display_size":4,"label":"PHONENO"},{"name":"HIREDATE","type":"DATE","display_size":10,"label":"HIREDATE"},{"name":"JOB","type":"CHAR","display_size":8,"label":"JOB"},{"name":"EDLEVEL","type":"SMALLINT","display_size":6,"label":"EDLEVEL"},{"name":"SEX","type":"CHAR","display_size":1,"label":"SEX"},{"name":"BIRTHDATE","type":"DATE","display_size":10,"label":"BIRTHDATE"},{"name":"SALARY","type":"DECIMAL","display_size":11,"label":"SALARY"},{"name":"BONUS","type":"DECIMAL","display_size":11,"label":"BONUS"},{"name":"COMM","type":"DECIMAL","display_size":11,"label":"COMM"}]},"data":[{"EMPNO":"000010","FIRST_NAME":"CHRISTINE","MIDINIT":"I","LASTNAME":"HAAS","WORKDEPT":"A00","PHONENO":"3978","HIREDATE":"1965-01-01","JOB":"PRES","EDLEVEL":18,"SEX":"F","BIRTHDATE":"1933-08-24","SALARY":52750.00,"BONUS":1000.00,"COMM":4220.00},{"EMPNO":"000020","FIRST_NAME":"MICHAEL","MIDINIT":"L","LASTNAME":"THOMPSON","WORKDEPT":"B01","PHONENO":"3476","HIREDATE":"1973-10-10","JOB":"MANAGER","EDLEVEL":18,"SEX":"M","BIRTHDATE":"1948-02-02","SALARY":41250.00,"BONUS":800.00,"COMM":3300.00},

... etc.

Documentation

PHP Composer command composer doc will use phpDocumentor to generate the API documentation.

Tests

PHP Composer command composer test will run the test cases. Currently, the test cases are limited to instancing the classes. (WIP)

Asynchronous support

This will be coming.
