Usage

Example of an array:

$arr = [
'a', 'b' => 'boo',
'c' => [
'c1',
'c2',
'c3'
],
'd' => [
'd1' => ['d1.1', 'd1.2'],
'd2' => ['d2.1', 'd2.2'],
'd3' => ['d3.1', 'd3.2'],
],
'e' => null,
'f' => false
];

Check the element by key(s)

Usage:

Collection::has(array $array, ...$keys);
array_has($array, ...$keys);

Examples:

array_has($array, 0); // true array_has($array, 'b'); // truearray_has($array, 'c', 0); // truearray_has($array, 'd', 'd1'); // truearray_has($array, 'e'); // truearray_has($array, 'f'); // truearray_has($array, 'g'); // false

Compare to isset():

isset($array['e']); // false

Get the element by key(s)

Usage:

Collection::get(array $array, ...$keys);
array_get(array $array, ...$keys);

Examples:

array_get($array, 0); // 'a' array_get($array, 'b'); // 'boo'array_get($array, 'c', 0); // 'c1'array_get($array, 'd', 'd1'); // ['d1.1', 'd1.2']array_get($array, 'e'); // nullarray_get($array, 'e', 'e'); // null

Add the element to the array by key(s)

Usage:

Collection::add(array &$array, $key, ...$values);
array_add(array &$array, $key, ...$values);

Examples:

array_add($array, 'c', 'c3'); // $array['c'][] = 'c3'array_add($array, 'd', 'd1', 'd1.3'); // $array['d']['d1'][] = 'd1.3'array_add($array, 'g', 'g1', 'g1.1'); // $array['g']['g1'][] = 'g1.1'// butarray_add($array, 'b', 'b1'); // InvalidArgumentException - $array['b'] is not an array

Set the element of the array by key(s)

This method is similar to native way.

Usage:

Collection::set(array &$array, $key, ...$values);
array_set(array &$array, $key, ...$values);

Examples:

array_set($array, 'g', 'game over'); // $array['g'] = 'game over';array_set($array, 'h', 'high way', 'e95'); // $array['h']['high way'] = 'e95';
