What best practices should be followed when naming custom functions to avoid conflicts with internal functions?

When naming custom functions to avoid conflicts with internal functions in PHP, it is best practice to use a unique and descriptive name for your function. One common approach is to prefix your custom function names with a unique identifier, such as your project name or initials, to reduce the likelihood of naming conflicts with internal PHP functions.

// Example of naming custom function with a unique prefix to avoid conflicts
function myproject_custom_function() {
    // Function logic here
}
