Your PHP project on which you want to develop

Objective: create a simple php project that is representative of a PHP project you might be working on. This project will serve as a support for the rest of the tutorial.

For the purpose of this tutorial we will create a simple PHP project consisting of a single PHP page index.php that will access a MySQL database containing a single table.

Creating the project file structure

Create the following file structure:

  • a parent folder docker-lampx.lateambichon.com
  • inside this folder create :
    • an empty file called index.php
    • a folder called .devcontainer
  • inside the .devcontainer folder create:
    • an empty file called Dockerfile
    • an empty file called docker-compose-.yml
    • a folder called docker
  • inside the docker folder create:
    • an empty file called docker-lampx.lateambichon.conf
    • an empty called dump_database.sql
    • an empty file called mod_deflate.conf

We will then see what these files and folders that we’ve just created correspond to.

index.php

Objective: This file will be used to:

  • as a support to demonstrate the debugging possibilities within a docker container
  • also it will demonstrate the possibility for a container to communicate with another container: communication with the MySQL container

Here is the source code of this file:

<?php
    $servername = "docker-mysql";
    $dbname = "dockerltb";
    $username = "dockerltb";
    $password = "password";

    try {
        $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
        // set the PDO error mode to exception
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        echo "<p>Connected successfully to database</p>"; 
    }
    catch(PDOException $e)
    {
        echo "<p>Connection to database failed: " . $e->getMessage() . "</p>";
    }
    echo "<p>This is team bichon!!!</p>";
    echo "<p>phpinfo() result :</p>";
    echo phpinfo();
?>

dump_database.sql

Objective: This file will be used to fill our MySQL database.

In practice, in your project, it can be a dump of the production database whose data you will have previously anonymized (or not :p), or any other useful dataset for your development environment.

/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;


DROP TABLE IF EXISTS `dockerltb`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `dockerltb` (
  `id` INTEGER NOT NULL,
  `content` varchar(100) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='List of possible actions';
/*!40101 SET character_set_client = @saved_cs_client */;

--
-- Dumping data for table `dockerltb`
--

LOCK TABLES `dockerltb` WRITE;
/*!40000 ALTER TABLE `dockerltb` DISABLE KEYS */;
INSERT INTO `dockerltb` VALUES (1,'This is the team!!!');
/*!40000 ALTER TABLE `dockerltb` ENABLE KEYS */;
UNLOCK TABLES;
