Doctrine\Common\Collections\ArrayCollection is a class implemented in the Doctrine Common library. It serves as a collection class that is used to store and manipulate arrays of objects that implement the Doctrine\Common\Collections\Collection interface. The ArrayCollection class implements many of the common operations that can be performed on collections such as filtering, sorting, and iterating.
Here are some code examples showing the usage of ArrayCollection:
// Creating an ArrayCollection object use Doctrine\Common\Collections\ArrayCollection;
$collection = new ArrayCollection();
// Adding items to the ArrayCollection $collection->add("item 1"); $collection->add("item 2"); $collection->add("item 3");
// Removing an item from the ArrayCollection $collection->remove("item 2");
// Sorting the ArrayCollection by value $collection->asort();
// Filtering the ArrayCollection by a callback function $filteredCollection = $collection->filter(function($value) { return strpos($value, "i") !== false; });
// Iterating over the ArrayCollection foreach($collection as $item) { echo $item . "\n"; }
These examples demonstrate some of the many operations that can be performed on an ArrayCollection. The Doctrine\Common\Collections\ArrayCollection class is part of the Doctrine Common library, which is a set of PHP libraries that provide commonly used functionality for object-relational mapping (ORM) and other PHP applications.
