Download the PHP package voku/arrayy without Composer

On this page you can find all versions of the php package voku/arrayy. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

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?

πŸ—ƒ Arrayy

A PHP array manipulation library. Compatible with PHP 7+ & PHP 8+

Installation via "composer require"

Multidimensional ArrayAccess

You can access / change the array via Object, Array or with "Arrayy"-syntax.

Access via "Arrayy"-syntax: (dot-notation)

Access via "array"-syntax:

Access via "object"-syntax:

Set values via "Arrayy"-syntax: (dot-notation)

PhpDoc @property checking

The library offers a type checking for @property phpdoc-class-comments, as seen below:

OO and Chaining

The library also offers OO method chaining, as seen below:

simple example:

complex example:

Implemented Interfaces

Arrayy\Arrayy implements the IteratorAggregate interface, meaning that foreach can be used with an instance of the class:

It implements the Countable interface, enabling the use of count() to retrieve the number of elements in the array:

PHP 5.6 Creation

As of PHP 5.6, use function is available for importing functions. Arrayy exposes a namespaced function, Arrayy\create, which emits the same behaviour as Arrayy\Arrayy::create(). If running PHP 5.6, or another runtime that supports the use function syntax, you can take advantage of an even simpler API as seen below:

Collections

If you need to group objects together, it's not a good idea to use a simple array or Arrayy object. For these cases you can use the class.

It will throw a if you try to add a non valid object into the collection.

e.g.: "YOURCollection.php" (see example on github)

You can also use "dot-notation" to get data from your collections e.g.

Pre-Defined Typified Collections

simple example

This will throw a "TypeError"-Exception.

complex example

This will NOT throw a "TypeError"-Exception.

Please see the {@see \Array} section of the manual for a detailed explanation of how arrays are implemented and used in PHP.

**Parameters:** - `int $mode [optional] If the optional mode parameter is set to COUNT_RECURSIVE (or 1), count will recursively count the array. This is particularly useful for counting all the elements of a multidimensional array. count does not detect infinite recursion.` **Return:** - `int

The number of elements in var, which is typically an array, since anything else will have one element.

If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is &null;, 0 will be returned.

Caution: count may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty array. Use isset to test if a variable is set.

For objects, if you have SPL installed, you can hook into count() by implementing interface {@see \Countable}.

Please see the {@see \Array} section of the manual for a detailed explanation of how arrays are implemented and used in PHP.

**Parameters:** __nothing__ **Return:** - `int

If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is &null;, 0 will be returned.

Caution: count may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty array. Use isset to test if a variable is set.
