Most developers use ten percent of Chrome DevTools. The Network waterfall, conditional breakpoints, why your CSS will not apply, and throttling that matches a real Indian 4G connection.

Most accessibility problems on a site come from about six mistakes. Semantic HTML, labels, focus, contrast and keyboard order — fixed in an afternoon, with real code.

Most small teams have a backup that has never been restored. The mysqldump flags that matter, where the copy must not live, the restore drill, and the runbook to write before you need it.

Sessions or tokens for your PHP app. How each one really works, why “JWT is stateless” is the worst reason to choose it, and a straight recommendation for a small team.

Why a custom property beats a Sass variable at runtime, how to build a token set, light and dark from one stylesheet, the three theme states, and the mistake that breaks half of them.

301 versus 302 and what the wrong one costs you, working rules for www, HTTPS and moved pages, how to spot chains and loops, testing with curl, and how to recover when a rule locks you out.

How WordPress sites actually get broken into, the nine hardening steps that matter, how to tell whether you are already compromised, and the order to work in if you are.

fetch does not throw on a 404 or a 500, which is why so many apps show the wrong error. The four failures to separate, timeouts, safe retries, and one wrapper that handles all of it.

Why an includes folder full of loose files stops working, Composer and PSR-4 from scratch, secrets outside the web root, and how to migrate a legacy project one folder at a time.

hasOne, hasMany, belongsTo, belongsToMany and hasManyThrough on a schema you would actually build – plus pivot columns, eager loading, withCount, and when a relationship is the wrong tool.
