Laravel 5: Attempt an Error-Prone Operation a Number of Times With retry
Learn how to use the retry helper function in PHP to attempt an operation that may throw exceptions multiple times. The retry function will retry the operation a specified number of times and can also introduce a delay between attempts. If the operation still fails after the specified attempts, an exception will be thrown.
Laravel 5: Comparing abort, abort_if, and abort_unless Helper Functions
The abort, abort_if, and abort_unless functions can be used to stop the execution of an application. They all achieve the same result, but abort_if and abort_unless have the advantage of being more readable and requiring less code. In the provided examples, these functions are used to check if a user has admin privileges and abort the execution if not. The choice of which function to use depends on personal preference and the semantics of the variable names.
Laravel 5: Conditionally Throwing Exceptions With throw_if
The throw_if function allows you to throw an exception when a given boolean value is true. You can pass additional parameters to the exception's constructor. In this example, an exception will be thrown if the supplied value is equal to 10.
Laravel 5: Conditionally Throwing Exceptions With throw_unless
The throw_unless helper function allows you to easily throw an exception if a condition evaluates to false. It takes in a boolean value and an exception class as parameters and throws a new instance of the exception if the boolean value is false. Parameters can also be passed to the exception's constructor if needed. An example use case is shown, where an exception is thrown if the supplied value is equal to 10.
Laravel 5: Conditionally Throwing HTTP Exceptions With abort_if
The abort_if helper function in Laravel is used to abort execution if a certain condition is met. It takes in a boolean argument and will abort if the argument supplied evaluates to true. This function is useful for performing a conditional check and calling the abort function in one line. An example use case would be to check if a user has admin privileges and abort with a 401 error code if not.
Laravel 5: Conditionally Throwing HTTP Exceptions With abort_unless
The abort_unless helper function is used to perform a conditional check and abort the execution of the application if the condition evaluates to false. This function allows you to combine the conditional check and the abort function in one line of code. An example use case is when you want to verify if a user has admin privileges and abort the execution with a 401 error code if they do not. The abort_unless function provides a clear and concise way to express this intent in your code.

Laravel 5: Decrypting Strings With decrypt
The decrypt helper function is used to decrypt a given value. It resolves the configured "Illuminate\\Contracts\\Encryption\\Encrypter" implementation from the Service Container and calls the decrypt method on the Encrypter instance. You can use the decrypt helper function or the Crypt facade to decrypt the value. Alternatively, you can resolve an instance from the Service Container using app('encrypter') or resolve('encrypter') and call the decrypt method on it.
