Template Engine: Build Your Own Blade
Render '{{ name }}' against your data the way every templating system does. The string-substitution engine behind every web page you have seen.
What you'll be able to build
Render '{{ name }}' against your data the way every templating system does. The string-substitution engine behind every web page you have seen. Along the way you pick up real, transferable PHP skills, not just this one project:
- preg_replace_callback for placeholders
- an associative array as the render context
- default values for missing keys
- escaping output safely
- building strings efficiently
- handling loops or sections

How the lessons actually work
Every lesson has you predict what a piece of PHP code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Template Engine, and a runnable proof page tied to your own code.
Common questions
How long does the Template Engine: Build Your Own Blade course take?
about 7 hours, across 6 modules and 28 lessons, at roughly 15 minutes per lesson. Your own course may run shorter or longer, since it's sized to your placement result, not a fixed template.
Do I need experience?
Some. This is an intermediate-tier PHP project, so it assumes you're comfortable with PHP basics and pushes past them.
How much does it cost?
$15 one-time, no subscription. The first module is free, so you can see exactly how the course teaches before you pay for the rest.
