PHP syntax checker

Paste a snippet to catch missing braces, quotes, and other structural issues the client checker can see. Code is not sent to a PHP runtime on FlashKit.

Always run `php -l` on the version you deploy (8.2 vs 8.4 differ).

How to Use

  1. Paste the file or function.
  2. Run the check and fix the first error — later ones may be cascade.
  3. Re-run. Then lint on your CI image.
  4. Never paste production .env contents.

Key Features

  • In-tab structural check
