CodeIgniter Deployment
In this chapter you will learn CodeIgniter Deployment. Globaltuts.com uses a simple lesson flow: explain the idea, show a working example, then highlight what to practice next.
This chapter is part of a longer track. Take your time, run every example locally, and use the Next link at the bottom when you are ready to continue.
What you will learn
- Define CodeIgniter Deployment in plain language and know when to use it
- See how CodeIgniter Deployment fits into PHP MVC apps with CodeIgniter controllers and models
- Study a complete example with expected output
- Avoid common beginner mistakes called out in this lesson
- Complete the practice checklist before moving to the next chapter
Before you start
Use a local editor and run examples in a safe test environment.
You do not need to memorize everything on the first pass. Focus on running the example and noticing how it fits into the bigger picture of real software projects.
Common mistakes to avoid
- Changing many lines at once so you cannot tell which change fixed or broke the output.
- Using outdated syntax from an old blog post instead of the track you are following on this site.
- Skipping the example and only reading the headings—typing code yourself catches gaps in understanding.
- Deploying tutorial snippets to production without validation, authentication, or security review.
Practice checklist
- Read the introduction once without typing, then read it again while following along.
- Run the example exactly as shown and confirm the output matches the preview.
- Change one variable or attribute and predict the result before refreshing.
- Write a two-sentence summary of CodeIgniter Deployment in your own words in a notes file.
Introduction
CodeIgniter Deployment is used when you work with PHP MVC apps with CodeIgniter controllers and models.
If you are new, do not rush. Re-read this section, then type the example manually instead of copy-pasting blindly.
Skip ahead only after you can explain today's idea in one sentence without looking.
Concept in depth
When you see CodeIgniter Deployment in documentation or on the job, it usually solves a specific problem: keeping PHP MVC apps with CodeIgniter controllers and models predictable, maintainable, and easy for others to read.
Compare the example below with the previous chapter in this track. Notice what changed and ask yourself why the author structured it that way.
Example
The sample below is intentionally small so you can see the core idea. Extend it only after you understand each line.
Match your output to the preview under the code block. If something differs, check typos, file paths, and whether you saved the file.
# Set CI_ENVIRONMENT = production in .env
# Point document root to /publicBelow is how the output typically looks in a browser, terminal, or API client:
Example ran successfully.
Explanation
Spend an extra minute on the line you understand least; that line usually shows up in the next chapter too.
Write a short note in your own words after each example so you remember why each line matters when you come back to this topic later.
