The csrf_field function simplifies the process of generating a hidden HTML element with the CSRF token value. It replaces the need for manually writing the HTML code and can be used in both PHP and Blade syntax. This makes it easier to include CSRF protection in your forms without cluttering your code.

The csrf_token() function in PHP is used to retrieve the CSRF token from the session storage. The token is a random 40-character string generated using the str_random(40) function. It can be used to enhance the security of HTML forms by including it as a hidden input field.

The decrypt helper function allows you to easily decrypt a given value. It resolves the configured Encrypter implementation and calls the decrypt method on it. Whether you use the Crypt facade or the decrypt helper function directly, the result will be the same.

Learn how to use the encrypt helper function in Laravel to encrypt a given value. This function resolves the configured Encrypter implementation from the Service Container and then calls the encrypt method on the Encrypter instance. Take a look at some example code to see how to use the encrypt helper with the Crypt facade or directly.

The env function in Laravel retrieves the value of an environment variable, returning the value if it exists or a default value if it does not. It supports automatic conversion of boolean string representations and null values to their respective PHP types. Examples are shown using a .env file, demonstrating the function's usage and defaults.

The info helper function in Laravel allows you to write information entries into the log files. You can specify a message and an optional context, which can be an array of data. The context can even contain objects. The log entries will include the message and the context data if provided.

The logger helper function in Laravel is a powerful tool for logging messages. If no message is provided, the function returns a Log instance. When used to write log messages, you can pass both a message and a context. The context can be an array, and even contain arrays or objects within it. The function will output log messages in Laravel's log files.

The session function in Laravel is a versatile function that can be used to return an instance of the SessionManager class, set session values, and retrieve session values. To return an instance of the SessionManager class, simply call the function without any parameters. To set session values, pass in an array of key/value pairs or use the put method to set a single session value. To retrieve session values, pass in the desired key to the function. If a session value does not exist, the function will return null, unless a default value is specified.

The first helper method in Laravel is used to retrieve the first key/value pair in an array that satisfies a given callback function. The callback function can be used to check if a value matches a specific format. If no key/value pair satisfies the callback function, a default value can be returned. The callback parameter is optional, and if omitted, the method will return the first item in the array. Additionally, there is a shortcut function called array_first which is equivalent to calling Arr::first.

The forget helper method in Laravel is used to remove items from an array using dot notation. It is a mutable function that affects the original array. You can remove single or multiple items by passing the keys as a string or an array. There is also a shortcut function called array_forget available in the global namespace.

The get helper method allows developers to quickly retrieve items from an array using dot notation, instead of PHP's array syntax. It is easier to read and can be customized with a default value. The array_get function is a shortcut to calling the Arr::get method in the global namespace.

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.

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.
