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?

GPT-3 Approximate Token Counter in PHP

This repository contains a PHP function that approximates the token count of a text string, following the tokenization rules used by OpenAI's GPT-3.

GPT-3, an advanced language model developed by OpenAI, reads text in chunks called tokens. A token in GPT-3 can be as short as one character or as long as one word (e.g., 'a', 'apple'). For languages with more complex scripts (like Chinese, Japanese, etc.), one character can be multiple tokens. Spaces and punctuation are also considered separate tokens.

The function provided here offers an approximation of how GPT-3 might tokenize a given string, counting words, spaces, and punctuation as separate tokens. This allows you to estimate the number of tokens in a text string without making an API call, which can be useful for monitoring usage or avoiding unnecessary costs.

Please note that this is a simplified approximation, and the actual tokenization may vary slightly in GPT-3's actual implementation. In particular, some words might be tokenized into multiple tokens if they contain special characters or are very long. Additionally, this method may not accurately tokenize languages other than English, especially those using non-Latin characters.

As of the last update in September 2021, OpenAI has not provided a public method for accurately counting tokens the way GPT-3 does. Therefore, this function is an estimation, not a guaranteed accurate count.
