Arrays
class Arrays
Array tools library.
Methods
Returns item from array. If it does not exist, it throws an exception, unless a default value is set.
Returns reference to array item. If the index does not exist, new one is created with value null.
Recursively merges two fields. It is useful, for example, for merging tree structures. It behaves as the + operator for array, ie. it adds a key/value pair from the second array to the first one and retains the value from the first array in the case of a key collision.
Returns zero-indexed position of given array key. Returns null if key is not found.
Tests an array for the presence of value.
Returns the first item from the array or null if array is empty.
Returns the last item from the array or null if array is empty.
Inserts the contents of the $inserted array into the $array immediately after the $key.
Inserts the contents of the $inserted array into the $array before the $key.
Renames key in array.
Returns only those array items, which matches a regular expression $pattern.
Transforms multidimensional array to flat array.
Checks if the array is indexed in ascending order of numeric keys from zero, a.k.a list.
Reformats table to associative tree. Path looks like 'field|field[]field->field=field'.
Normalizes array to associative array. Replace numeric keys with their values, the new value will be $filling.
Returns and removes the value of an item from an array. If it does not exist, it throws an exception, or returns $default, if provided.
Tests whether at least one element in the array passes the test implemented by the
provided callback with signature function ($value, $key, array $array): bool.
Tests whether all elements in the array pass the test implemented by the provided function,
which has the signature function ($value, $key, array $array): bool.
Calls $callback on all elements in the array and returns the array of return values.
Invokes all callbacks and returns array of results.
Invokes method on every object in an array and returns array of results.
Copies the elements of the $array array to the $object object and then returns it.
Converts value to array key.
Returns copy of the $array where every item is converted to string and prefixed by $prefix and suffixed by $suffix.

mergeTree(array $array1, array $array2)
