The method where() allows users to filter collection items given a key-value pair. This method filters items by checking whether the $key has some value equal to provided $value.

You can also pass a parameter to control how method compares $key with $value. Laravel runs the given command and returns a new collection of instances containing filtered items that satisfied the condition.

Structure of where()

Illuminate\Support\Collection class provides an easy, accessible wrapper for working with arrays of data.

/**
 * Filter items by the given key value pair.
 *
 * @param  string  $key
 * @param  mixed  $operator
 * @param  mixed  $value
 * @return static
 */
public function where($key, $operator = null, $value = null)
{
    ...
}
