CVE-2026-109618 and CVE-2026-109619 (PHP2Shell) are two critical PHP flaws rated 9.2 on CVSS v4.0. Both went public and were patched on October 21, 2026, four days after an exploit attempt was recorded, and official fixes ship only for PHP 8.2 and later. A SvelteKit front end, with any remaining server code on a patched runtime, ends the exposure, and most small and mid-sized sites move in 7 days. See how PHP2Shell works.
PHP to Svelte migration services rebuild the screens your US customers see as small, compiled Svelte components, usually with SvelteKit handling routing and server rendering. They suit companies whose PHP templates have become slow to load and painful to change, and every working feature stays in place.
Svelte is a compiler, which sets it apart from React and Vue. Your components turn into lean, plain JavaScript at build time, so the browser downloads no heavy framework runtime. For a PHP site that ships jQuery plus a pile of plugins on every page, the drop in page weight shows clearly in Lighthouse.

Reasons to rebuild a PHP front end in Svelte
Svelte suits teams that want fast pages and readable code without the size and ceremony of bigger frameworks.
Lighter pages
Compiled components and no virtual DOM mean less JavaScript on the wire, which helps Core Web Vitals on mobile connections.
Less code to maintain
A Svelte component keeps markup, script and scoped CSS in one short file, and reactive state needs far fewer lines than jQuery DOM juggling.
Server rendering kept
SvelteKit renders pages on the server and can prerender static ones, so search engines still get full HTML, as they did from PHP.
What the Svelte rebuild covers
- Every public page rebuilt as SvelteKit routes
- Forms moved to SvelteKit form actions with server-side validation
- Login, sessions and user roles carried over
- PHP business logic turned into API endpoints or SvelteKit server code
- MySQL data kept, with queries moved behind a clean API layer
- Shared layouts, header and footer as reusable components
- Old URLs preserved, with 301 redirects for anything that moves
- Deployment to Node hosting, Vercel or your own server with SSL
How the 7-day Svelte move runs
Day 1: Map the site
Every template, form, database table and outside service is listed and sorted into API or page, then you sign off a fixed price.
Days 2-4: Build in SvelteKit
Developers set up the SvelteKit layouts and components and wire each route to your data through load functions.
Days 5-6: Compare and check
Each page is checked side by side with the PHP version for content, forms and speed, and you review it on a staging link.
Day 7: Switch over
DNS or the reverse proxy moves to the new app, redirects go live, and the team monitors errors and traffic after launch.
PHP templates vs SvelteKit
How the same site behaves before and after the rebuild.
| PHP pages | SvelteKit app | |
|---|---|---|
| Page interaction | Full reload or hand-written jQuery | Client-side navigation with reactive components |
| JavaScript size | jQuery plus plugins on every page | Only the compiled code each route needs |
| Styling | Global CSS that breaks in surprising places | Component-scoped styles by default |
| Forms | Posted to a PHP file, logic mixed with HTML | Form actions that work even without JavaScript |
| SEO | Server HTML | Server HTML plus prerendering for static pages |
| Security patching | Tied to the PHP version on the host | Node runtime and npm packages updated on their own cycle |

Frequently asked questions
Straight answers about our PHP to Svelte Migration service.
Most small and mid-sized PHP sites move to SvelteKit in 7 days: a day of mapping, three of building, two of checks and launch on day seven. Bigger apps move in phases, with the order set during the audit.
No. A sound PHP side can stay as a JSON API on patched PHP 8.4, with Svelte handling only the front end. Old, fragile PHP logic moves into SvelteKit server routes instead.
Yes. Svelte is open source, actively maintained and used in production by large publishers and product teams. Its hiring pool is smaller than React's, so the code stays plain and documented for any JavaScript developer to pick up.
If your team already knows React well, or you depend on a React-only component library, a React or Next.js rebuild may be the better call. The audit will say so plainly.
Yes, when handled with care. Crawlers still receive full server-rendered HTML with the same content as before. Titles, meta tags and URLs stay, and 301 redirects cover changed paths.
Yes. A single project manager runs the work, with an NDA before anyone sees code if you want one and call times inside the US Eastern workday.
Is your PHP app still on an old version?
Send the URL or repository, under NDA if needed. The audit checks for the PHP2Shell flaw and outdated code and shows what a 7-day migration looks like.
