How can PHP developers effectively debug and troubleshoot issues related to variable assignment and data processing in scripts?

Issue: To effectively debug and troubleshoot variable assignment and data processing issues in PHP scripts, developers can use var_dump() or print_r() functions to display the contents of variables, check for typos or syntax errors in variable names, and use error_reporting() function to display errors. Code snippet: 

// Debugging variable assignment
$variable = 'value';
var_dump($variable);

// Troubleshooting data processing
$data = ['apple', 'banana', 'cherry'];
foreach($data as $item){
  echo $item . '<br>';
}
