How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a BIM (Building Information Modelling) developer with PHP with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

BIM (Building Information Modelling)
BIM (Building Information Modelling)
Building Information Modelling (BIM) is the modern way of managing all the information required for a construction project with a single, structured, digital 3D model, through to the demolition of a building. The most important aspect of BIM is that it is not only a model but structured data relating to every component of the building through to when it is eventually demolished. BIM facilitates the flow of information throughout the various stages of a construction project.
Key Features of BIM:
Extensive Component Information: Unlike the simple meshes of 3D modelling, BIM models include extensive embedded metadata – e.g. a modelled wall could have properties such as the building materials, paint specification, manufacturing cost, etc, which can be used to automatically generate material bills and verify element compatibility.
Interdisciplinary Collaboration: BIM allows for greater collaboration between architects, engineers, and the construction team as part of the building process. Everyone creates the model, and every element is checked accordingly to allow designers to build under budget and schedule.
Interoperability with Industry Software: The leading software for BIM, Autodesk Revit, has come to become synonymous with BIM, as it has been adopted by the industry and is now the de-facto industry leader. Using Revit a great deal of detail can be modeled of specific architectural and structural elements such as walls, floors, and pipework with greater accuracy.
Usage Across Industries: BIM was first used in architecture and structural engineering, but it is now becoming more apparent across industries within civil engineering and construction. It is most suited for commercial construction where it can help verify estimates and help contractors install various systems.
Lifecycle Management: One key part of BIM for Facility Management is the holistic management of the lifecycle of a building. That is, not only is construction information provided, but also maintenance, operation, and demolition information. This ensures the whole lifecycle is managed effectively, and ensures that all of the relevant project information is available to those who need it, at the appropriate stage of the project.
Operational Uses of BIM:
Design and Pre-Construction.Modelling is completed by architects and engineers for each discipline in the digital realm, and used to generate drawing and specifications for construction.
Construction and Fabrication. Contractors use artefactual models, the specialised fabrication models, which shape the work of construction, to help coordinate the fitting together of the myriad components.
Post-construction. The as-built BIM models guide facility managers and maintenance crews during the running and management of the building, offering a point of reference that improves the speed and accuracy of renovation or repair work.
What is there in the future?
Finally, BIM is becoming part of the solution to more global urban and infrastructural challenges by integrating BIM with Geographic Information Systems (GIS) – a new elevation, sometimes called City Information Modeling (CIM), that extends the benefits of BIM from the level of the building to the level of the city. These benefits will help solve some daunting problems, such as how to design a city where traffic flows freely but vehicles have minimal carbon footprints, how to maintain networks, and how to make healthcare more accessible.
With the expected massive influx of urban populations by 2050, the role of digital models in urban planning and management is set to become more central than ever, and BIM and CIM more important tools for the construction and civil engineering sectors.
Where is PHP used?
WordPress: The Website Warlock
- Once upon a byte, PHP conjured WordPress, the magical platform where websites spring to life with a couple of clicks.
Facebook: The Social Spellcaster
- Believe it or not, the social giant Facebook began its journey swiping right to PHP, casting status and friend request spells.

PHP Alternatives
Node.js
Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code server-side, making it possible to use JavaScript for full-stack development.
// Simple Node.js server
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
- Non-blocking I/O enables high throughput
- Unified programming language (JavaScript) for client and server side
- Vast npm ecosystem with numerous packages
- Callback-heavy "hell" can lead to complex code
- Heavy computational tasks can block the event loop
- API is not as stable as in more mature back-end languages
Python with Django
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. It's known for its ease of use and a "batteries-included" philosophy.
# Simple Django view
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world. You're at the polls index.")
- High-level framework streamlines web development
- Strong emphasis on reusability and "pluggability" of components
- ORM for database abstraction
- Can be slower for performance-intensive tasks
- Monolithic framework can be overkill for small projects
- URL routing can be tricky for beginners
Ruby on Rails
Ruby on Rails, or just Rails, is a server-side web application framework written in Ruby under the MIT License. Rails is a model-view-controller (MVC) framework, providing default structures for a database, a web service, and web pages.
# Simple Rails controller
class WelcomeController < ApplicationController
def index
render html: "Hello, world!"
end
end
- Convention over configuration reduces setup time
- Integrated testing tools enhance reliability
- Active community and gem ecosystem
- Can be seen as too magical for beginners
- Boot speed and runtime performance may be slower
- Less favorable for microservice architecture
Quick Facts about PHP
PHP: A Scripting Saga Begins
Picture it: 1994, the interwebs were still a gangly teenager, and along comes Rasmus Lerdorf. This guy wasn't planning to change the digital world, mind you — he just wanted to track visits to his online resume (talk about self-promotion!). Thus, he birthed "Personal Home Page/Forms Interpreter" or PHP/FI. Who knew that his little script baby would grow up to power a huge chunk of the web, including a juggernaut we call Facebook?
Version Schmersion: PHP Evolves
Fast forward a bit, and PHP's hitting version milestones faster than a toddler learns new words. PHP 3 comes out in 1997, and suddenly everyone's like, "Wait, we can use this for serious stuff?" Then the pivotal PHP 4 arrives in 2000 with the Zend Engine strapped to its back, giving it a nitro boost in speed and reliability. The weird part? Each major version seems to hang around longer than those leftovers in the back of your fridge. I'm looking at you, PHP 5.
From Rasmus with Love: PHP's Handy Gift to Coders
<?php
// PHP letting you slip in and out of HTML like a ninja
echo "<p>Hello, sneakily embedded code!</p>";
?>
This right here is a slice of PHP's party trick — seamlessly jumping in and out of HTML. Early on, Rasmus gifted programmers something akin to a Swiss Army knife in web development. You could churn out dynamic web pages without breaking a sweat. Crank out an echo statement here, mix in some HTML there, and voilà! You've got yourself a website that does the cha-cha.
