What is null in PHP?

In PHP, a variable with no value is said to be of null data type. Such a variable has a value defined as NULL. A variable can be explicitly assigned NULL or its value been set to null by using unset() function.

In PHP, null is a special value that represents the absence of any value or the lack of a specific data type. It is often used to indicate that a variable or an expression does not currently hold a valid value or does not reference any object or data.

Here are some key points to understand about null in PHP:

Initialization: When a variable is declared but not assigned a value, it is automatically assigned null by default. Type and Comparison: null is considered a separate data type in PHP. It is not equivalent to an empty string (“”) or zero (0). To check if a variable is null, you can use the === or is_null() comparison operators. 

• Default Function Behavior: If a function or method parameter has a default value of null, it means that the argument can be omitted when calling the function, and the default null value will be used. Developers can then check if the argument is null within the function and handle it accordingly.
• Unset and Nullify: The unset() function can be used to destroy a variable, removing it from memory. After unsetting a variable, it becomes null. Similarly, you can assign null to a variable explicitly to indicate that it no longer holds a valid value. 
• Database Handling: null is commonly used in database interactions. It represents the absence of a value or a missing data field. When retrieving data from a database, columns that have no value or are not specified are often returned as null.
• Conditional Statements: null can be used in conditional statements to determine whether a variable has a value or not. It allows developers to handle different scenarios based on whether the value is present or absent.

What is boolean in PHP?

Definition and Usage. This is one of the scalar data types in PHP. A boolean data can be either TRUE or FALSE. These are predefined constants in PHP. The variable becomes a boolean variable when either TRUE or FALSE is assigned.

Here are some key points to understand about booleans in PHP:

• Values: The boolean data type has two possible values: true and false. true represents a condition that is considered true or a positive state, while false represents a condition that is false or a negative state.
• Logical Operators: Booleans are commonly used in combination with logical operators (&& for AND, || for OR, and ! for NOT) to evaluate complex conditions. These operators allow developers to combine multiple boolean expressions and make decisions based on the resulting boolean value.
• Comparison Operators: Comparison operators (==, ===, !=, !==, <, >, <=, >=) are often used to compare values and generate boolean results. For example, comparing two numbers with the greater than (>) operator will return true if the first number is indeed greater than the second.
• Conditional Statements: Booleans play a crucial role in conditional statements, such as if, else if, and while loops. These statements evaluate boolean expressions and execute specific code blocks based on the resulting boolean value. 
• Function Return Values: Functions can also return boolean values. Developers can define custom functions that perform certain operations and return true or false based on the outcome. This allows for reusable code that can be conditionally executed based on the returned boolean value.
• Type Conversion: PHP also supports type juggling and automatic type conversion. When evaluating non-boolean values in a boolean context (such as within an if statement), certain rules determine their conversion to boolean. For example, an empty string (“”), 0, null, and an empty array are considered false, while non-empty values are considered true.

Booleans are fundamental in programming and are used extensively in decision-making, conditionals, loops, and other control flow structures. Understanding how to work with booleans enables developers to create robust and dynamic PHP applications that respond to different conditions and logic.

What is PHP made of?

Created in 1994 by Rasmus Lerdorf, the very first incarnation of PHP was a simple set of Common Gateway Interface (CGI) binaries written in the C programming language.

• PHP Parser: At the heart of PHP is its parser, which analyzes PHP code and converts it into a format that can be executed by the PHP engine. The parser parses the PHP script line by line, identifies the structure and syntax, and generates an intermediate representation called the “Abstract Syntax Tree” (AST).
• Zend Engine: The Zend Engine is the core execution engine of PHP. It takes the AST generated by the parser and interprets it, executing the PHP code line by line. The Zend Engine handles tasks like memory management, variable handling, and garbage collection. It is responsible for the overall execution and performance of PHP scripts.
• Standard PHP Library (SPL): SPL is a collection of classes and interfaces that provide a set of standard data structures, algorithms, and utilities. It includes classes for handling arrays, iterators, data filtering and validation, file handling, and more. SPL enhances the functionality of PHP by providing a consistent and reusable set of components.
• Extensions: PHP has a modular architecture that allows for the integration of extensions. Extensions are additional libraries or modules that provide specific functionalities and extend the core capabilities of PHP. Examples of extensions include database extensions like PDO and MySQLi for database connectivity, XML extensions for working with XML data, and image manipulation extensions like GD and Imagick.
• Libraries and Frameworks: PHP has a vast ecosystem of libraries and frameworks that developers can leverage to streamline web development. Libraries like Symfony, Laravel, and CodeIgniter provide pre-built functions, components, and tools for common web development tasks, enabling developers to build robust and scalable applications more efficiently.
