Laravel 5: Getting Array or Object Values With data_get
The data_get function is a versatile tool that allows you to retrieve values from both objects and arrays in PHP. It has the same behavior as the array_get and object_get functions, but it accepts both objects and arrays as its $target input value. You can also supply a default value to use if the key doesn't exist in the target. The function is easy to use and can greatly simplify your code when working with both objects and arrays.
Laravel 5: Getting the Class Name for an Object Instance With class_basename
Learn how to use the class_basename function in PHP to retrieve the name of a class. The function accepts a class and returns its base name. Check out the provided examples to see how it works with different classes and objects.
Laravel 5: Getting the Current Date and Time With now
The now helper function in PHP returns a new Carbon instance that represents the current date and time. It can also accept an optional timezone parameter to adjust the timezone of the returned date. Learn how to use the now helper function with an example that shows how to get the current Atom formatted date and time, as well as how to get the current date and time for a specific timezone.
Laravel 5: Provide Default Values for Object Properties With optional
The optional function in Laravel returns a new instance of Illuminate\Support\Optional with the provided value. It allows you to easily retrieve a default or null value on method return values or object properties that may not exist. This can be useful when displaying data or returning results that might not exist at runtime. The Optional class also implements the Illuminate\Support\Traits\Macroable trait, allowing you to add functionality to the Optional instance at runtime.
Laravel 5: Retrieving Object Values With object_get
The object_get function allows developers to retrieve properties from a given object using dot notation. It is useful when the existence of a specific property in the object cannot be guaranteed. With object_get, you can easily access nested properties of an object. If a property does not exist, you can provide a default value to be returned instead.
Laravel 5: Retrieving the Default Value of a Given Variable With value
The value function in PHP retrieves the default value of a given variable. If the variable is an anonymous function, it will be executed and the resulting value will be returned. Otherwise, the function will simply return the variable as is. An example using an anonymous function and another example using a regular variable are provided.
Laravel 5: Returning In-line Access to a Variable With with
Learn how to use the with function in PHP to simplify method chaining and return values without creating temporary variables. The with function can be helpful when passing new class instances as function arguments. It can also accept a callback function to perform additional actions or mutate the value before returning it. An alternative to the with function is wrapping object instantiation within parentheses. The with function can improve code readability and clarify intent. Use the example provided to learn how to get a weather forecast using the Yahoo weather API and the with function.
Laravel 5: Setting Array or Object Values With data_set
The data_set function allows you to set the value of an item in an array or object property using dot notation. It accepts a reference to the target array or object, the key of the data to set, and the value to be set. By default, existing values for the key will be replaced, but you can choose to overwrite or not. The function can also handle nested properties and can be used with objects as well.
Laravel 5: Setting Data on Objects Without Overwriting Existing Data With data_fill
The data_fill helper function is used to set data in a target object. It is similar to the data_set helper function, but it does not overwrite existing data. The function takes three parameters: the target object, the key to set, and the value to set. When called, data_fill internally uses data_set with the overwrite flag set to false. An example use case is demonstrated where data is set using both data_fill and data_set with the same result.
Laravel 5: Accessing and Manipulating Configuration Values With config
The config function in Laravel can be used to resolve an instance of the configuration repository from the Service Container, or to get or set configuration values at runtime. It has multiple signatures allowing for different usage scenarios. When used without any arguments, it returns an instance of the configuration repository. The function can also be used to set configuration values by providing an array of key/value pairs, and it can retrieve configuration values by providing a key, with an optional default value if the key does not exist.
