How do we recognize a good programming ?

  • Readability
  • Time complexity
  • Space complexity
  • Reusability
  • Code coverage for deployment

How to onboard a developer in your team ?

Onboarding tools

1 – Assist them in having their work environment ready

#1 –  create a company email for new employee

#2 –   Provide a GIT repository account

#3 –  provide local development environment – Sandboxes account

#4 – provide Jira Account / access

#5 – provide Confluence account

#6 –  provide VPN access

#7 –  provide Chat/Slack access

2- Guideline Programming

3 – Recommendation for integrating  developers in the group

*  pull request / code review against programming guideline

*  write functional test on the latest/pending release

* write documentation phpdocs / swagger / add documentation

4 – Programming guideline

 Principles are guiding this methodology

- Readability
- Quality Assurance
- Logic
- Reusable code


PSR-2 code styling
Function no longer than 50 lines
PHP doc Block
TypeHint your functions
More information:

For better code readability we suggest PSR-2 code styling to be applied. We consider a function bigger than 25 lines is not an efficient function. For engaging this methodology we recommend 50 lines maximum per function. DocBloc are essentials. Swagger in a case of API writing is essential to be present.
A developer should be able to explain his work easily and quickly and should use materials to do so

Quality Insurance

No PHP error message
No PHP Warning messages
No PHP Notices
No hardcore credentials
Unit Testing

When executing the code we expect the quality assurance team to verify that no PHP errors, warnings, notices are produced. We also expect the QA team to go throughout the code to verify that no hardcore credentials are present within the code. Unit Test writing should be edited by QA team preferably


DRY (do not repeat yourself)
KISS (Keep it Stupid Simple)
SOLID principles

 Reusable Code

Use PHP throw exception
Use Object oriented techniques
Use static function

Use PHP throw exception
Use Object oriented techniques
Use static function

Add the following your PHP too get rid of PHP notices, warnings

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);

How to Fibonacci iteratively ?

Using Iteration

 public static int fibonacciLoop(int nthNumber) {
        //use loop
        int previouspreviousNumber, previousNumber = 0, currentNumber = 1;

        for (int i = 1; i < nthNumber ; i++) {

How to write Basic algorithms such as BFS and DFS in php ?

Find basic algorithms in the link here

DFS – Depth First Search


class Node{

  public $children = array();
  public $name = '';
  public function __construct(string $nameNode){
    $this->name = $nameNode;
  public function isLinked(Node $node):bool{
    foreach($this->children as $c){
      if($c->name === $node->name){
        return true;
    return false;

  public function linkTo(Node $node):Node{
    //Todo  verify if already linked
    $this->children[] = $node;
    return $node;
  public function notVisitedArray(array $visitedArray):array{
    $notVisited = array();
    foreach($this->children as $c){
        $notVisited[] = $c;
    return $notVisited;

$node1 = new Node('1');
$node2 = new Node('2');
$node3 = new Node('3');
$node4 = new Node('4');


//$r = $node1->notVisitedArray(array('1'));
 // print_r($r);


function dfs(Node $node, 
             string $path = '',
             array $visited = array()): void{

  $visited[] = $node->name;
  $notVisited = $node->notVisitedArray($visited);
  if(sizeOf($notVisited) === 0){
    echo 'path: '.$path.'->'."$node->name"."\n\r";  
    return ;
  foreach($notVisited as $key => $n){
    dfs($n, $path.'->'.$node->name, $visited);

BFS – Breadth First Search


$graph = [
    'A' => ['B', 'C'],
    'B' => ['A', 'D'],
    'D' => ['B'],
    'C' => ['A',],

//bfs($graph, 'A', 'D'); // true
//bfs($graph, 'A', 'G'); // false
print_r(bfs_path($graph, 'A', 'D')); // ['A', 'B', 'D']

function bfs_path($graph, $start, $end) {
    $queue = new SplQueue();
    # Enqueue the path
    $visited = [$start];
    while ($queue->count() > 0) {
        $path = $queue->dequeue();
        # Get the last node on the path
        # so we can check if we're at the end
        $node = $path[sizeof($path) - 1];
        if ($node === $end) {
            return $path;
        foreach ($graph[$node] as $neighbour) {
            if (!in_array($neighbour, $visited)) {
                $visited[] = $neighbour;
                # Build new path appending the neighbour then and enqueue it
                $new_path = $path;
                $new_path[] = $neighbour;
    return false;

How to renew PAF of a NCOA ?

When hitting the following endpoint

If you have the following error :

 </SOAP-ENV:Envelope>HTTP/1.1 500 Internal Server Error

 <faultstring>Error 0x800404B4: Your Processing Acknowledgement Form (PAF) expired on 09/11/2021.  You must file a new form with your NcoaLink vendor before processing can continue.</faultstring> 

please do the following

If you look in  C:\Program Files (x86)\Satori Software\BCC Architect\Developer Center (United States)\Sample Code\move\NETClasses\csharp\Move_CSharp\bin\Release
If you click on Run Move Update, the Move Agent Wizard will pop up, and here is where you can renew your PAF.

What restful api method would be appropriate for an upsert ?

Create/Update endpoint in a restful api

The PUT API methodology should be appropriate for an upsert

According to the HTTP specification:

The PUT method requests that the enclosed entity be stored under the supplied Request-URI. If the Request-URI refers to an already existing resource, the enclosed entity SHOULD be considered as a modified version of the one residing on the origin server. If the Request-URI does not point to an existing resource, and that URI is capable of being defined as a new resource by the requesting user agent, the origin server can create the resource with that URI.

I therefore think that the use of PUT for an insert or update is perfectly legitimate, provided that in both cases the URI is known in advance. If you’re using the key as part of the URI (as k1 in this should be the case. To be ideally RESTful, however, a GET to the same URL should also allow you to download the resource.

How to onboard new developer/programmer in your team?

Well let’s start by having them

#1 – writing functional test. They should be able to write functional test that can cover the knowledge transfer explained

#2 – Writing phpdoccs to document the code. They could as well document existing swagger documentation via phpdocs with Zircote for API platform

#3 – Initiate their work through a git pull request
this will trigger a code Review policy
