Laravel Array Helper Function: Checking If a Key Exists in an Array or Collection
The exists helper method in Laravel can be used to check if a specified key or index exists in a given array. It is similar to PHP's array_key_exists function. The method requires two parameters: the array to check and the key/index to search for. The method returns true if the key/index exists and false otherwise. The method supports arrays, collections, and other values that return true from the Arr::accessible helper method.
Laravel Array Helper Function: Determining If a Value Is An Array
The accessible helper method determines if a given value is array accessible. In other words, it checks if the value is an array or an instance of ArrayAccess. This is useful for checking if a variable can be accessed using array syntax. The method can be used with various types of values, as shown in the provided examples.
Laravel Array Helper Function: isAssoc (Checking If An Array Is Associative)
The isAssoc helper method can determine if an array is associative or not. According to the provided documentation, an array is considered associative if it doesn't have sequential numeric keys starting from zero. However, in practice, the behavior can be slightly different. For example, [0,1,2,3] is not considered associative, while ['associative' => 'array'] is.
Laravel Helper Function: bcrypt
The bcrypt function in PHP is used to generate a hashed representation of a given value. It accepts an optional array of options which can affect how the hash is computed. Each time bcrypt is called, it will produce a different result, even if the input remains the same. The rounds option can be used to control the number of iterations, with a default value of 10. Increasing the number of rounds will also increase the time required to compute the hash.
Laravel Helper Function: config
The config helper function in Laravel is a versatile function that can be used to access, set, and retrieve configuration values. When called without any arguments, it returns an instance of the Illuminate\Config\Repository class, allowing you to check if a config item exists. If you provide an array as the key, you can set multiple configuration values at once. And when you provide a non-array key, you can retrieve a configuration value, with an optional default value if the key doesn't exist. Use this helper function to conveniently handle your application's configuration.
Laravel Helper Function: cookie

It does not send the cookie to the client, only creates it. The function has seven optional parameters including the name, value, expiration time, path, domain, secure flag, and httpOnly flag. Examples of creating cookies with different options are provided.
