EnumeratesValues.php
TLDR
This file is part of the Illuminate\Support\Traits namespace and contains the EnumeratesValues trait. The trait provides methods for working with collections, such as filtering, mapping, reducing, and iterating over the items.
Methods
make
Creates a new collection instance from the given items.
wrap
Wraps the given value in a collection if applicable.
unwrap
Gets the underlying items from the given collection if applicable.
empty
Creates a new instance with no items.
times
Creates a new collection by invoking the callback a given amount of times.
average
Calculates the average value of the collection.
some
Checks if any item in the collection satisfies the given condition.
dump
Dumps the items in the collection.
each
Executes a callback over each item in the collection.
eachSpread
Executes a callback over each nested chunk of items in the collection.
every
Checks if all items in the collection satisfy the given condition.
firstWhere
Gets the first item in the collection that matches the given key value pair.
value
Gets a single key's value from the first matching item in the collection.
ensure
Ensures that every item in the collection is of the expected type.
isNotEmpty
Checks if the collection is not empty.
mapSpread
Runs a map over each nested chunk of items in the collection.
mapToGroups
Runs a grouping map over the items in the collection.
flatMap
Maps the items in the collection and flattens the result.
mapInto
Maps the values in the collection into a new class.
min
Gets the minimum value of a given key in the collection.
max
Gets the maximum value of a given key in the collection.
forPage
"Paginates" the collection by slicing it into a smaller collection.
partition
Partitions the collection into two arrays using the given callback or key.
percentage
Calculates the percentage of items in the collection that pass a given truth test.
sum
Gets the sum of the values in the collection.
whenEmpty
Applies a callback to the collection if it is empty.
whenNotEmpty
Applies a callback to the collection if it is not empty.
unlessEmpty
Applies a callback to the collection unless it is empty.
unlessNotEmpty
Applies a callback to the collection unless it is not empty.
where
Filters the items in the collection by the given key value pair.
whereNull
Filters the items in the collection where the value for the given key is null.
whereNotNull
Filters the items in the collection where the value for the given key is not null.
whereStrict
Filters the items in the collection by the given key value pair using strict comparison.
whereIn
Filters the items in the collection by the given key value pair using the "in" operator.
whereInStrict
Filters the items in the collection by the given key value pair using strict comparison and the "in" operator.
whereBetween
Filters the items in the collection by the given key value pair where the value is between the given values.
whereNotBetween
Filters the items in the collection by the given key value pair where the value is not between the given values.
whereNotIn
Filters the items in the collection by the given key value pair using the "not in" operator.
whereNotInStrict
Filters the items in the collection by the given key value pair using strict comparison and the "not in" operator.
whereInstanceOf
Filters the items in the collection, removing any items that do not match the given type(s).
pipe
Passes the collection to the given callback and returns the result.
pipeInto
Passes the collection into a new class.
pipeThrough
Passes the collection through a series of callable pipes and returns the result.
reduce
Reduces the collection to a single value.
reduceSpread
Reduces the collection to multiple aggregate values.
reduceWithKeys
Reduces an associative collection to a single value.
reject
Creates a new collection of items that do not pass a given truth test.
tap
Passes the collection to the given callback and then returns it.
unique
Returns a new collection with only unique items.
uniqueStrict
Returns a new collection with only unique items using strict comparison.
collect
Collects the items into a new collection.
toArray
Gets the collection of items as a plain array.
jsonSerialize
Converts the object into something JSON serializable.
toJson
Gets the collection of items as JSON.
getCachingIterator
Gets a CachingIterator instance.
__toString
Converts the collection to its string representation.
escapeWhenCastingToString
Indicates whether the model's string representation should be escaped when __toString
is invoked.
proxy
Adds a method to the list of proxied methods.
__get
Dynamically accesses collection proxies.
