How can PHP developers effectively troubleshoot and resolve issues related to variable interpretation in PHP code?

Issue: PHP developers can effectively troubleshoot and resolve issues related to variable interpretation by ensuring that variables are properly declared and used within the code. This includes checking for typos, ensuring variable scope is correct, and verifying that variables are properly concatenated or interpolated within strings. Example PHP code snippet: 

$name = "John";
$age = 25;

// Correct variable interpolation within a string
echo "My name is $name and I am $age years old.";

// Correct variable concatenation within a string
echo 'My name is ' . $name . ' and I am ' . $age . ' years old.';
