Guides that nest the way PHP tags do.
Velqoralex writes PDF guides to PHP — from your first script to how the Zend Engine executes your code. Each guide names exactly what it covers, and nothing it doesn't.
Written for readers, not for launches.
Velqoralex started as internal onboarding notes for developers joining a PHP codebase, written because most tutorials assumed too much or explained too little. Every guide is a standalone PDF: real code, explained in the order a working application actually uses it, with no chapter that exists just to pad the page count. We don't publish anything we wouldn't hand to someone joining our own team.
Ten guides, in the order most readers use them.
What you actually get.
One PDF, yours to keep
Every guide is delivered as a single downloadable PDF. No account, no app, no subscription to cancel.
Content lists, not blurbs
Every product page lists the actual modules inside the guide, so you know what you're paying for before you buy.
Fixed, listed prices
Prices don't move around a countdown timer. What's on the page is what you pay.
Start free, go deeper later
The Free Capsule is a genuine starting point, not a sales page. There's no obligation to buy anything after it.
Frequently asked
What format do the guides come in?+
Every guide is a PDF. You'll get a download link after payment, and the same link is emailed to you as a backup.
Do I need to read them in order?+
No, but they're written that way. Each guide builds on ideas from earlier ones, so if you're new to PHP, starting with the Free Capsule will make the later ones easier going.
Which PHP version do the guides target?+
All examples are written against a current, supported PHP release and avoid syntax that's specific to one point release wherever possible.
How do I pay?+
Each product's "Buy" button takes you to a secure payment page for that guide. Once payment is confirmed, you'll get your download link.
What if I'm not happy with a guide?+
