How can we access the value of a private property in a class?
To access the value of a private property in a class, we need to understand the concept of encapsulation in object-oriented programming. Encapsulation is a fundamental principle that allows us to control access to class members, such as properties and methods. In PHP, we can achieve encapsulation by using access modifiers. In PHP, we have
What is the purpose of making properties private in a class?
In the realm of web development, specifically in the context of PHP and MySQL, the concept of classes and objects plays a crucial role in organizing and structuring code. One fundamental aspect of classes is the ability to define properties, which are essentially variables that hold data. When designing classes, developers often make use of
Why are cookies considered a useful tool in web development for persisting and tracking data between different pages on a website?
Cookies are widely considered a useful tool in web development for persisting and tracking data between different pages on a website. They serve as a means to store small pieces of information on the client's browser, allowing websites to remember user preferences, track user behavior, and maintain session state. In the field of web development,
What is the difference between cookies and sessions in web development?
In the field of web development, cookies and sessions are two commonly used mechanisms for maintaining user data and state between HTTP requests. While they serve a similar purpose, there are distinct differences between cookies and sessions in terms of how they store and manage data. Cookies are small text files that are stored on
What is the purpose of using sessions in web development?
Sessions play a crucial role in web development, particularly in the realm of PHP and MySQL. They serve as a mechanism for maintaining stateful information between multiple requests made by a single user.

What other information can be accessed from the `$_SERVER` super global? Give an example of how to access this information.
The `$_SERVER` superglobal in PHP provides access to various server and execution environment information. It contains an array of key-value pairs, where each key represents a specific server variable and its corresponding value holds the information associated with that variable. This superglobal is available in all scopes throughout the PHP script, making it a convenient

It provides information about the type of HTTP request made to the server. This variable is commonly used in web development to determine the action to be taken based on the type of request. The value
How can a ternary operator be used to assign a value to a variable?
A ternary operator is a conditional operator that allows for the assignment of a value to a variable based on a condition. In PHP, the ternary operator takes the form of "condition ? value_if_true : value_if_false". It is a concise way to write if-else statements and can be used to assign a value to a
