FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package debug-utils

survos/debug-utils

Assertion helpers that show the acceptable values on failure — not just "key not found".

When a CSV header, API payload, or config array has the wrong key, the mistake is almost always a typo, an underscore-vs-hyphen, or a capitalisation slip. A plain array_key_exists check tells you name is missing; these helpers tell you name is missing and here are the keys that do exist — so you spot emial next to email instantly.

Intentionally a dev-only dependency. Do not require it in production code.

Requirements

Installation

Usage

All helpers are static methods on Survos\DebugUtils\Assert and throw \InvalidArgumentException on failure.

keyExists() — one key must be present

Accepts arrays or objects, and string or integer keys. The available keys are sorted, so the output is stable across runs.

keysExist() — several keys must all be present

inArray() — value must be one of an allowed set

Comparison is strict, so '1' is not accepted where 1 is allowed.

Custom messages

Every helper takes an optional trailing $message appended to the failure output:
