How can PHP functions be called in a way that avoids the error message "Call to undefined function"?

When the error "Call to undefined function" occurs in PHP, it means that the function being called has not been defined or included in the current scope. To solve this issue, you can ensure that the function is defined or included before calling it. This can be done by including the file that contains the function definition or ensuring that the function is defined in the same file where it is being called. 

// Include the file that contains the function definition
include 'functions.php';

// Call the function after including the file
myFunction();
