About PHP
The real skills of 2025-2030 are: Can you make the server do useful work before the page reaches the browser?
PHP is server-side glue for real websites.
Forms, sessions, includes, templates, files, mail, databases, login checks, admin pages, and business workflows can all be handled clearly with PHP.
This is a primer. Jit-PHP shows the practical skills behind server-side web logic, not just terms copied from a list.
Part 1
Procedural PHP
Learn how PHP pages run from top to bottom, how functions organize work, and how real server-side programs handle forms, files, sessions, and data.
✓ Lesson 1 Free • No Login Required
Variables That Remember Things
Variables let PHP hold names, numbers, choices, totals, and other working information.
$name = "Rick";
$total = 25;
$total = 25;
Making Decisions In PHP
PHP uses if, else, comparisons, and logic to choose what should happen next.
if ($age >= 18) { }
Repeating Work In PHP
Loops let PHP process lists, rows, files, form fields, and repeated jobs.
foreach ($contacts as $contact)
Functions Build Programs
Functions keep one job in one place so procedural PHP stays readable and fixable.
function clean_text($value)
Breaking PHP Into Files
Includes let one program use shared headers, menus, config files, and function libraries.
require_once "functions.php";
Forms Talk To PHP
Learn how browser form data reaches PHP through GET and POST.
$_POST["email"]
Saving Information With PHP
PHP can save data in files, CSV, JSON, or a database so information survives after the request ends.
file_put_contents()
Sessions Build State
HTTP forgets. Sessions help PHP remember a user across more than one request.
session_start();
$_SESSION["user"]
$_SESSION["user"]
