A free PHP echo, variables and errors test for Years 10–11 (ages 14–16): 12 questions, marked instantly – write, fix and predict real PHP code in your browser. No sign-up. This test is for Years 10–11 (ages 14–16).
Before you start
12 questions on echo, strings, variables, var_dump(), warnings and errors, picked from a bank of 54 each time. Some questions ask what a program prints or which message PHP shows; some ask you to put lines in order, fill in a trace table, or write or fix a short program. When you write or fix code, press Run to try it. It is marked when you move on: your program is run in your browser against the example and some hidden tests (other values and other form data). Choose Practice to see the answer after each question, or Test to see your answers at the end.
- 12 questions – a new mix each time you try
- PHP runs in your browser – nothing to install (the first code question downloads PHP once, about 3 MB)
- A keyboard helps for the coding questions
No sign-up and no adverts. Your answers and your code stay on this device. Nothing you type in the test is sent to us – unless you choose to report a problem with a question.
How it is marked: Classfern's own checks, in your browser. Code is run in a locked box against tests, some of them hidden; nothing is marked by a person or by guesswork. Spot a mistake? Use the Report button.
