What are the potential pitfalls of using PHP functions in a specific order?

Potential pitfalls of using PHP functions in a specific order include unexpected results, errors, or unintended behavior due to dependencies between functions. To avoid these issues, it's important to ensure that functions are called in the correct sequence to maintain the expected flow of the program.

// Example of calling functions in a specific order to avoid pitfalls
$result1 = function1();
$result2 = function2($result1);
$result3 = function3($result2);
// Continue with the rest of the program
