Laravel Array Helper Function: array_has
The has helper method in Laravel allows you to check if a specific key exists in an array using dot notation. It returns a boolean value indicating the existence of the key. This method is particularly useful for arrays with arbitrary depth and is easier to use than PHP's isset function. Additionally, there is a shortcut function called array_has that can be used instead of calling Arr::has.
Laravel Array Helper Function: array_last
The last helper method in Laravel is used to retrieve the last element in an array that satisfies the given callback function. If no value satisfies the callback, a default value can be provided as well. An example usage of this method is demonstrated, showing how to get the last post from an array based on a specific format. The optional callback parameter can be omitted, in which case the method will simply return the last item in the array. Additionally, there is a shortcut function called array_last available in the global namespace that performs the same functionality as Arr::last.
Laravel Array Helper Function: array_pluck
The pluck helper method is a convenient way to extract specific values from an array. It can be used with arrays of objects or arrays of arrays. The method can also return an array with a key/value pair based on the specified key. Additionally, pluck supports dot notation to search for keys at arbitrary depths in nested arrays or objects. There is also a global array_pluck function, which is a shortcut to calling Arr::pluck.
Laravel Array Helper Function: array_pull
The pull helper method in Laravel is used to retrieve and remove a value from an array based on a specified key. It is similar to the get method, but with the additional functionality of removing the item from the array. This function is mutable and will affect the original array.
Laravel Array Helper Function: array_set
The set helper method allows you to set values within an array using dot notation for the key. It is the opposite of the forget method. The set function mutates the original array and can be used to change the entire array or replace it with a different type. There is also a shortcut function called array_set available in the global namespace to call Arr::set.
