PHP String Objects

PHP String Objects is a library that provides an easy and intuitive interface for working with PHP arrays and objects. With built-in validation and filtering, it makes it easier to access, manipulate and validate data, saving you time and frustration.

Allows accessing objects via strings
Allows checking if the values of objects are valid using pre-defined or custom validation rules
Provides middleware functionality to set memory limits or other configurations
Provides data filters to manipulate the values of objects
Can be used to set or get values of objects and arrays in a simplified manner

Installation

To install the library, run the following Composer command:

composer require uuur86/strobj

USAGE

To get started with PHP String Objects, include the following code at the top of your PHP file:

use StrObj\StringObjects;
require('vendor/autoload.php');

BASIC USAGE

Here is an example of how to use PHP String Objects to access and manipulate data in a JSON string:

use StrObj\StringObjects;

require('vendor/autoload.php');

// String JSON data to be used
// or you can use an object/array
$persons = '{
    "persons": [
        {
            "name": "John Doe",
            "age": "twelve"
        },
        {
            "name": "Molly Doe",
            "age": "14"
        },
        {
            "name": "Lorem Doe",
            "age": "34"
        },
        {
            "name": "Ipsum Doe",
            "age": "21"
        }
    ]
}';

$test = StringObjects::instance(
