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 string-similarity

string-similarity

Finds degree of similarity between two strings, based on Dice's Coefficient, which is mostly better than Levenshtein distance.

This implementation actually treats multiple occurrences of a bigram as unique. The correctness of this behavior is most easily seen when getting the similarity between "GG" and "GGGGGGGG", which should obviously not be 1.

This is a PHP implemenation of the Node.js package string-similarity

Usage

Install using:

In your code:

API

The package contains two methods:

compareTwoStrings(string $string1, string $string2, bool $casesensitive)

Returns a fraction between 0 and 1, which indicates the degree of similarity between the two strings. 0 indicates completely different strings, 1 indicates identical strings. The comparison is case-sensitive by default.

Arguments
  1. string1 (string): The first string
  2. string2 (string): The second string
  3. casesensitive (bool): If the comparison should be case-sensitive

Order does not make a difference.

Returns

(number): A fraction from 0 to 1, both inclusive. Higher number indicates more similarity.

Examples

findBestMatch(string mainString, array targetStrings, bool $casesensitive)

Compares mainString against each string in targetStrings.

Arguments
  1. mainString (string): The string to match each target string against.
  2. targetStrings (array): Each string in this array will be matched against the main string.
  3. casesensitive (bool): If the comparison should be case-sensitive.
Returns

(Object): An object with a ratings property, which gives a similarity rating for each target string, a bestMatch property, which specifies which target string was most similar to the main string, and a bestMatchIndex property, which specifies the index of the bestMatch in the targetStrings array.
