What are the best practices for avoiding conflicts with other programming languages when writing PHP code?

To avoid conflicts with other programming languages when writing PHP code, it is essential to use proper naming conventions, avoid reserved keywords in other languages, and be mindful of syntax differences. Additionally, using namespaces and prefixes can help differentiate PHP code from code written in other languages.

// Example of using namespaces to avoid conflicts with other programming languages
namespace MyPHPCode;

class MyClass {
    // PHP code here
}
