PHP Testing
Testing for PHP: Tests the code they wrote, not the code they meant.
Who it is for
Tests the code they wrote, not the code they meant.
The behaviour people get wrong after they are already productive in the language.
You will get the most out of it if you have written PHP recently enough to read it without effort, and have been surprised by it at least once. If you are picking the language up for the first time, start with PHP Essentials and come back to this one.
How long it takes
Planned at 90 graded questions, which is about 68 minutes of answering and roughly 18 days at five a day.
Nothing ships until every runnable snippet in it has been executed and matched against its answer.
Syllabus
What you will be asked about
This course is in production
It is planned as ten topics of ten questions, the same shape as every other course in the catalogue: one concept card, six multiple-choice questions, one predict-the-output, one ordering task and one matching task per topic. The topics themselves are mined from PHP Language Reference, and nothing is listed here until the questions exist and have been executed — a syllabus written before the content is a promise, and this page only carries facts.
Free and paid courses are decided per course, not per language, and this one will be included in a subscription.
