How can PHP developers effectively debug and troubleshoot issues related to function declarations in their code?

To effectively debug and troubleshoot issues related to function declarations in PHP code, developers can start by checking for syntax errors, ensuring proper naming conventions, and verifying the function is being called correctly. Using debugging tools like var_dump() or print_r() can help inspect variables and outputs during runtime. Additionally, utilizing error reporting functions like error_reporting(E_ALL) and ini_set('display_errors', 1) can provide more detailed error messages. 

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

function myFunction($param) {
    // function logic here
}

// call the function
myFunction($argument);
?>
