The `Collection.contains` function is used in PHP to determine whether a collection (such as an array or iterable object) contains a specified value. It takes two parameters: the collection to search in, and the value to look for. If the value is found in the collection, the function returns `true`; otherwise, it returns `false`. This function can be helpful when you need to check if a certain value exists in a collection before performing any further operations.
