Notes that became guides.
Velqoralex is a small, independent publisher of PDF guides to PHP. We don't have a course platform, a certificate, or a community forum — just guides, written to be read once and kept as reference.
Where this started
The first guide we wrote was for two developers joining a PHP codebase mid-project. Most tutorials we found either assumed too much or padded simple ideas into long chapters to look substantial. We wrote something shorter and more direct instead, and kept doing that as the topics got harder.
What we actually sell
Ten PDF guides, priced individually, covering PHP from your first script through to how the Zend Engine executes your code, with OPcache and PHP-FPM tuning along the way. Nothing is bundled behind a subscription, and nothing is sold on urgency — the catalogue looks the same today as it will next month.
What we don't promise
We don't promise a job, a salary figure, or a timeline for "becoming a PHP developer." What each guide promises is narrower and more honest: a specific set of topics, explained clearly, with working code you can run yourself.
How the guides are written
Every guide starts as working code, not prose. We write and test the examples first, then write the explanation around them. If an example doesn't run cleanly on a current, supported PHP release, it doesn't go in the guide.
