I'm fairly new to PHP development and I'm trying to understand the basic data types in PHP. I have some experience in other programming languages, but I want to make sure I understand the specific data types used in PHP.
From what I've gathered so far, PHP supports several basic data types, including:
1. Integer: These are whole numbers without any decimal points. I assume they can be positive or negative.
2. Float: These are numbers with decimal points, also known as floating-point numbers. I believe they can represent both whole and fractional values.
3. String: This data type is used to store textual data, such as names, addresses, and any other sequence of characters.
4. Boolean: This represents a binary value, either true or false. I assume it's used for conditions and logic operations.
5. Array: I'm familiar with arrays from other languages, but I'm curious about their usage in PHP. Are there any specific characteristics or features I should know about?
6. Object: I understand that PHP is an object-oriented language, so I assume objects can be created and manipulated using this data type.
7. Resource: I've come across this term, but I'm not exactly sure what it means. Can someone explain what a resource is in PHP and how it is used?
These are the data types I'm aware of, but I wanted to make sure I haven't missed anything important. If there are any additional data types in PHP or if there's anything else I should know about these basic data types, I would really appreciate your insights.
Thank you in advance!
