Mood Meter: Rate Any Line of Text
Score any line of text as positive, negative, or neutral by building the same lexicon-and-weights approach real sentiment tools use, then hand back a confidence, not just a label.
What you'll be able to build
Score any line of text as positive, negative, or neutral by building the same lexicon-and-weights approach real sentiment tools use, then hand back a confidence, not just a label. Along the way you pick up real, transferable PHP skills, not just this one project:
- an associative array as a word-to-weight lexicon
- tokenizing with str_split and strtolower
- array_reduce for a running score
- clamping a score into a confidence range
- match for labeling the verdict
- returning structured, testable feedback

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 Mood Meter, and a runnable proof page tied to your own code.
