FAQ
Example:
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 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.

Different tools for arrays in PHP.
Dependencies

Installation
Install with Composer:
Map Class
This class provides a wrapper class for indexed arrays and implements \ArrayAccess, \Countable and \Serializable Interfaces.
Usage
Refer namespace
create new Map
available options:
recursive-> create instance recursive (automatically create Map or Collection instance from array values)key_locked-> only allow keys which are already defined in Map.
Methods
get($key, $default = null)
Returns property value by given key or returns $default if property does not exist.
has($key)
Determine if an property with given key exists in the map.
set($key, $value)
Set property (override if existing). Returns map instance.
remove($key)
Remove property if existing. Returns map instance.
only()
returns Map with all items with given keys.
except()
returns Map with all items except with given keys.
toArray()
Returns all items as array.
toSerializedArray()
Returns serialized items (call $item->toSerializedArray() if item is object and has this method) as array.
toJson()
Returns all items of the map as JSON string.
merge(array $data, $prefer_old = false)
Merge given array (or Map instance) into map data.
If $prefer_old is true, the data will be merged in the opposite direction.
Returns map instance.
copy()
Returns clone of Map instance.
clear()
Removes all items map and returns instance of map.
each(\Closure $call)
Walk through map items.
You can break by return false in the closure.
Returns map instance.
map(\Closure $call)
Walk through map items and overrides there values by the return value of the given closure.
Returns collection instance.
Collection Class
This class provides a wrapper class for indexed arrays implements \ArrayAccess, \Countable, \Iterator and \Serializable Interfaces.
available options:
recursive-> create instance recursive (automatically create Map or Collection instance from array values)
Usage
Refer namespace
create new Collection
Methods
toArray()
Returns all items of the collection as indexed array.
toSerializedArray()
Returns serialized Items (call $item->toSerializedArray() if item is object and has this method) as array.
toJson()
Returns all items of the collection as JSON string.
copy()
Returns clone of collection instance.
getKeys()
Returns an array of collection item keys.
hasKey(int $key)
Determine if an item with given key exists in the collection.
isEmpty()
Determine if there are no items in the collection.
getValues()
Returns an array of Collection items. (actually the same like toArray() because collection data is always an indexed array)
hasValue(int $value)
Determine if an item with given value exists in the collection.
count()
Returns the count of items in the collection.
clear()
Remove all item from the collection. Returns collection instance.
get(int $key)
Returns the collection item with the given key.
remove(int $key, bool $do_not_clear = false)
Remove the collection item with the given key. Returns collection instance.
each(\Closure $call)
Walk through collection items.
You can break by return false in the closure.
Returns collection instance.
filter(\Closure $call)
Walk trough collection items and only keep items where closure returns true.
reverse()
Reverse the items in the collection. Returns collection instance.
first()
Returns the first collection item.
last()
Returns the last collection item.
shift()
Returns and removes the first collection item.
unshift(mixed $value)
Push an item onto the beginning of the collection. Returns collection instance.
pop()
Returns and removes the last collection item.
push(mixed $value)
Push an item onto the ending of the collection. Returns collection instance.
put(int $key, mixed $value)
Put an item in the collection by key. (Override if existing) Returns collection instance.
inject(int $key, mixed $value)
Put an item in the collection by key. (move items one possition up where key >= given key) Returns collection instance.
merge(array $array)
Merge given array (or Collection instance) into collection data. Returns collection instance.
sort(\Closure $call)
Sorts the collection items with usort
Returns collection instance.
map(\Closure $call)
Walk through collection items and overrides them by the return value of the given closure.
Returns collection instance.
slice(int $offset, int|null $length = null)
Slize the collection data with array_slice. Returns collection instance.
chunk(int $size)
Returns an array of collections with given chunk size.
current(int $size)
Returns item on current pointer position or 'null' if there is no item.
next(int $size)
Increase internal pointer by one and returns the item or 'null' if there is no item on this position.
previous(int $size)
Decrease internal pointer by one and returns the item or 'null' if there is no item on this position.
setPointer(int $pointer)
set the internal pointer position to the given value.
lists(array $keys)
returns an array with given array entries/public properties of collection items.
join(string $glue)
